Comment (by mikeperry):

 I am having trouble finding the branch that matches those line numbers
 exactly, but those asserts are checking to see if cells were written due
 to timers firing. If not re-initting libevent was causing timers not to
 fire, that would explain those test assert fails.

 The backtrace assert is also hard to tell. Is chan null, or is
 channels_pending NULL? It might make sense that channels_pending was NULL
 if libevent never got set up properly for anything to ever get written?

 Or is the backtrace still happening and is something different?

 (Also, do we have jenkins bots to watch for this? I don't see any for
 freebsd, unless they are just named weird).
