5899 panic on bad mutex in smb_event_wait()
There was an ordering problem in tear-down of the "events" support

and these "threshold" things. I never liked the smb_event stuff.

It's a global event list largely duplicating the functionality of the old-style

unix sleep/wakeup (on an address) mechanism. It was not needed here,

so the use of events was removed, and the wait implemented using a

simple cv_timewait() instead.
Internal reviewers were:

Verfied the fix by forcing smbd to core dump and making sure the smbsrv module doesn't panic.

Has also been in the field for quite a while.
