	- USR1/USR2 believed working now.

	- lbd crashes believed fixed.
	- Add the first attempt at USR1/USR2 support in lb, to make it
	   stop talking to the network but not completely lose
	   synchronization.  Doesn't work right yet.

	- Add LB_STATUS message, to allow lbd to keep a dashboard.

	lbd usually crashes when I SIGHUP it.  I'm investigating.

	- Supports SIGHUP to make lbd reread its config.
	- Fix blank lines in lbd config file.
	- Make lbd set its RLIMIT_NOFILE soft limit to its hard limit.
	- Add LB_SIZE message, so client can tell server what size the
	   backup file should have; make server use it.

	The LB_SIZE change introduces possible version-skew issues.  A
	new server is compatible with old clients, but a new client
	running against an old server will see the connection drop at
	the end of the initial sync-up scan.  (It will then reconnect,
	rescan, and see it drop...over and over.  The server will gripe
	about an unrecognized message type as it drops.)

	Current version as of BSDCan talk, 2005-05-13.
	Baseline for this changelog.
