  Log Message:
  -----------
  event-loop:  Remove dead code, make sure win-dispatcher handles all events.

Remove aggressiveness and some #if 0 priority code from event loop.
Neither is a good idea in my mind...the aggressiveness was playing dangerous
tricks just to save a gettimeofday call, and the prioritization could cause
priority inversion locks as implemented.

Update win-dispatcher to make sure to process all descriptors that have events
on them each time we do a wait-and-dispatch.  This should increase fairness
on heavily loaded systems.

Add debug logic to eventloop to print out cases where things take longer than
expected.  Need more debugging in this area to find out exactly what is
causing the slowdowns...
