Hi,

The following patch changes sysmon_taskq to use mutexes and condvars.

I had to use two spin mutexes to handle the queue and finalization, as
the former may be called from interrupt context and I can't acquire an
adaptive mutex while I'm in the spinning one.

It's working great with LOCKDEBUG/DIAGNOSTIC/DEBUG... please review.

Cheers.
