o Minor bugfixes: - Don't log inappropriate heartbeat messages when hibernating: a hibernating node is _expected_ to drop out of the consensus, decide it isn't bootstrapped, and so forth. Fixes part of bug 7302; bugfix on 0.2.3.1-alpha. - Don't complain about bootstrapping problems while hibernating. These complaints reflect a general code problems, but not one with any problematic effects. (No connections are actually opened.) Fixes part of bug 7302; bugfix on 0.2.3.2-alpha.
