Matt,

	I looked a little more at the BSD/OS mutex macros. I
see that we don't do a recusrion check first even when it
has been flaged as likely. This does seem less than perfect.
I'll flip this stuff around as well as undoing the lock prefix
on releasing spin locks. I'll let you know what happens.


Chuck
