*	add clock module	tv	18 hours	18	-75/+164
\| \| \| \| \|	The Clock module is the system clock that every unix timestamp new goes through. It comes with an offset that only tests can set.
*	add stalled source test	tv	19 hours	2	-3/+40
\|
*	avoid stalled source	tv	19 hours	3	-2/+28
\| \| \| \| \| \| \| \| \| \| \| \| \|	A source given up for not answering our sync messages could become the source again straight away. Whoever asks first after the reset takes the role, and that's often the same peer, which would then stall for another delivery limit. Now, a stalled source isn't chosen again for one more delivery_limit. If it's the only candidate, catching up waits that long and then tries it again. Before, a retry with that peer couldn't have helped any sooner anyway: a source is only given up after a whole delivery limit without a sync message, and that clock restarts when it is chosen again.

*	warn about unresolvable seeds once; log success	tv	28 hours	1	-7/+22
\|
*	genesis conflicts seeds or recover-from	tv	28 hours	1	-16/+19
\| \| \| \| \|	genesis together with seeds or recover-from is now an error wherever the values come from, and not settled by precedence.
*	add disk I/O stats	tv	28 hours	6	-27/+138
\|
*	add possibility to start with a document	tv	28 hours	4	-13/+163
\| \| \| \|	The --recover-from option allows a node start with a given document.
*	add state file	tv	30 hours	7	-4/+266
\| \| \| \| \|	This allows storing the swarm ID and additionally discovered seeds, which prevents a formerly genesis node to start a new document.
*	put swarm ID into the document	tv	30 hours	4	-6/+27
\|
*	add genesis flag and never give up	tv	30 hours	3	-76/+112
\| \| \| \| \| \| \| \| \|	The --genesis flag has been introduced to start with a new document. This prevents restarts to accidentally start with a new document and accept reads/writes, causing a second swarm to appear. Additionally, bootstrapping doesn't timeout anymore as that's of no use for nobody.
*	compact remake fixes base at the commit	tv	43 hours	5	-40/+138
\| \| \| \| \| \| \|	Instead of fixing base heads at when proposed, compact fixes them when committing. This shrinks the window where writes can be lost if their author restarts to the switch delay; during replace and import remakes writes can still be lost during the voting period.
*	fix wording around swarm key admission	tv	44 hours	2	-3/+3
\|
*	allow superseding expired remakes	tv	44 hours	4	-26/+279
\|
*	remake coordinators resume after restart	tv	44 hours	3	-5/+49

*	add votes register	tv	45 hours	8	-124/+507
\|
*	bound stable-hub degree	tv	46 hours	1	-4/+46
\| \| \| \| \| \|	Each stable member can be preferred at most by 4*k members. The budget is spent in key order, which is the same on every node, so the graph stays deterministic, symmetric and connected.
*	coalesce announcements	tv	46 hours	3	-2/+60
\|
*	cache heads	tv	46 hours	7	-24/+61
\| \| \| \|	To reduce the number of write locks, heads are now cached.
*	corroberate newer epochs	tv	46 hours	1	-11/+53
\|
*	follow and download from ready members only	tv	46 hours	3	-3/+29
\|
*	being caught up needs some heads	tv	47 hours	1	-5/+9
\| \| \| \| \| \| \| \| \| \| \|	A sync message from a ready peer only completes the initial sync if that peer has at least one head. A peer with an empty document can no longer make a joiner ready on an empty store: a misconfigured second swarm, or a genesis node in its first seconds. Effect on a brand-new swarm: a joiner now waits until the genesis node has registered itself in the member list, which happens within about 5 s of it becoming ready.

*	put remake content into blobs	tv	2 days	15	-79/+319

*	add configuration files	tv	2 days	4	-107/+1261
\|
*	wire up --mycelium-tcp-listen-port	tv	2 days	1	-2/+5
\| \| \| \| \|	It wasn't used before, causing the supervised daemon to always pick a random one.
