System: NetBSD azarin 1.4P NetBSD 1.4P (AZARIN) #84: Wed Dec 1 21:54:14 JST 1999 kei@azarin:/a/anoncvs/netbsd/src/sys/arch/macppc/compile/AZARIN macppc


>Description:
	cdrecord calls mlockall(2) with argument MCL_CURRENT|MCL_FUTURE, but
	it always returns EAGAIN on my environment and causes the program exit.

	I tried to maximize the resource limit with built-in ulimit of sh, but
	got no success.
>How-To-Repeat:
	make cdrecord 
>Fix:
	I commented out mlockall call and it works on my macppc box (XXX see:
	pkg/9506) and sparc classic.  macppc has 160MB of RAM and sparc 32MB.

	the new patch-af is attached below.
