>Description:

	On both 2.0_BETA and -current, pagedaemon will consume unreasonable
	amounts of CPU when doing anything "serious" (i.e., spawning a vi
	process, compiling anything from pkgsrc, and so forth).  This results
	in system stalls (on machines with large amounts of memory) and
	spontaneous reboots (when memory is exhausted).
	
>How-To-Repeat:

	Install NetBSD/amd64.  Start top.  Start a lengthy compile.  Watch
	the pagedaemon process jump up to the top of the process list; the
	machine should start freezing shortly thereafter.

>Fix:

	Not sure.  Something clearly isn't right ...
