kernel - Fix probable callout race
* Fix a probable callout race in kern/kern_event.c. It is possible
for the callout to be requeued during teardown and for the
structure to subsequently become corrupted.
Manifests as 'stuck' processes (still ^C'able if PCATCH is flagged),
and sleeps which do not expire. Can be triggered by synth bulk runs.
* Increase maximum number of kqueue timers from 4096 to 65536. This
limit will have to be moved to uidinfo (but not in this commit).
