	A timing bug was found in relation to VMS 5.x and SMP at the University
	of Western Ontario. Apparently the 3 CPUs of the 6230 provided
	just the right sequence of events for this to show up.

	The following PATCH is (strongly) recommended for any SMP or 
	ASMP VAXes currently running FUSION 3.3


	$ set default fns_base:[bin]
	$ link/map/full/noexe fustart.stb 	! Ignore warning message
	$ edit fustart.map
		search for 'os_fwq_rem' and write down hex location
		(Assume for this *example* the location is C12345)

	$ patch fustart.exe
	$ define os_fwq_rem=C12345	! Remember C12345 is ONLY AN EXAMPLE
	$ deposit/instruction os_fwq_rem+29
	'bicl2 #7,R0'
	'rsb'
	exit
	update
