Hm.  If there's an infinite loop there, it *probably* means that the
event list for that fd has become corrupt.  One reason that can happen
is if you add an event, then re-assign it and re-add it without first
deleting it.  To debug that, try enabling debug mode by calling
     event_enable_debug_mode();
near the start of your program (before you construct any event_bases).

It should detect any attempts to modify an event that's currently pending.

HTH,
