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?
