>Description:
	Recently (I think since going to 1.2 alpha), I've been
	getting really weird CPU resource utilisation figures from
	my shell's (tcsh) "time" command.  I've also noticed the
	same thing with /usr/bin/time, so it doesn't seem to be
	some misinterpretation on tcsh's behalf.

	I've getting output like the following:

	382.351u 3962.609s 0:50.00 8689.9% 0+0k 0+0io 0pf+0w
	2306.537u 14909.980s 0:46.90 36708.9% 0+0k 0+2io 0pf+0w
	2640.456u 27579.969s 51:09.11 -414.-7% 0+0k 49+851io 284pf+0w

	The problem doesn't occur all of the time - at a guess I'd
	say about 50% of the time...

	I've only noticed this problem on the pmax port - at least
	I haven't seen it on i386, which is the only port I have
	access to.
>How-To-Repeat:
	Type "time <command>" for commands that use a reasonable
	amount of cpu time ("make" and "make clean" down in /usr/src
	somewhere are good choices.
>Fix:
	Unknown.
