>Release:        FreeBSD 2.1.7-RELEASE i386
>Environment:

	FreeBSD 2.1.7, XFree86 3.2

>Description:

	xsysinfo seens to lose control under high load condition.

>How-To-Repeat:

	- Create a program to eat LOTs of memory, effectively trashing
	the whole system.  This program must disable all limits on
	memory alocation and RSS size.  If necessary, I have such a
	program.
	- Start X and xsysinfo
	- Run the memory eater, eat all RAM your machine have, forcing
	everything to go to swap.
	- xsysinfo stops refreshing, and consumes 100% of your CPU.

>Fix:
	
	I did not look at the sources, but I think it's a problem with
	linked lists acessing /dev/kmem.  NetBSD's identd had this
	problem.
