Perhaps it's just me, but I've had trouble setting ITIMER compiling
VMs (3.1a-4164 and 3.2b-something; i'm in the wrong universe to look
right now) on FreeBSD-4.5-STABLE and HPUX11. What seems to happen is
that the vm seems to stall (0% cpu) when doing i/o and receiving X11
events wakes it up. Annoying to have to wiggle the mouse to get the
SUnits to run :) I looked at it some but got waylaid by Work. Hope to
get back to it next week.
Has anyone else seen this behavior?
