Change 33442 by rwatson at rwatson_paprika on 2003/06/20 08:59:33

	First pass (untested): BSD SMPng condition variables implemented
	in terms of Mach wait_queue's and mutexes.  This will allow us
	to avoid extensive changes to the synchronization primitives
	used in the MAC Framework by providing semantically similar
	(identical?) functionality.  Not every CV function is
	implemented, but enough for the MAC Framework to work.
