Could we do something about the logging?

I have a couple of bugs filed already but in addition it would be nice
to have a usable debug mode.
The problem right now is that when enabled the logs fill up with

Apr 15 18:42:29 pcmk-1 corosync[4913]:   [TOTEM ] mcasted message
added to pending queue
Apr 15 18:42:29 pcmk-1 corosync[4913]:   [TOTEM ] Delivering da to dc

which redundantly redundant, not terribly informative and so verbose
that syslog ends up dropping most of corosync's logs anyway:

Apr 15 18:42:29 pcmk-1 rsyslogd-2177: imuxsock lost 644 messages from
pid 4913 due to rate-limiting
Apr 15 18:42:35 pcmk-1 rsyslogd-2177: imuxsock lost 664 messages from
pid 4913 due to rate-limiting

600+ messages being thrown away at a time is pretty bad.
Adding in the messages that /did/ make it to the logs between the two
times, corosync is pumping out messages at more than 390 per _second_.
