Note that there was a recent bug fix in HEAD that fixed a race where if you 
were using a callout that rescheduled itself and didn't do an explicit 
callout_stop() while holding the lock but just did a callout_drain(), then 
the callout could remain scheduled.  The latest commit to kern_timeout.c 
should fix this though.
