Log Message:
ugen(4): Use cv_wait loop for draining reference count on detach.
- Should be no need to use cv_timedwait because all users have now
been given a wakeup (previously writers were not, so we relied on
the timeouts to work out).
- Need to run this in a loop or else a spurious wakeup could cause us
to free data structures before the users have actually drained.
