   So, PHOLD()/PRELE() affect, basically, the U-area/kernel stack.  Now,
   it is true that UBC causes processes to be more aggressive swapped out
   (thich needs to be fixed separately), and the PHOLD() would prevent

I wonder if this sort of thing is related to something I'v seen.....

I'v noticed a problem with vmware on a 1.5.1_BETA machine.  The box will
lock up solid if there is any real swapping going on and vmware is
running.  The lock up will often times be triggered by other attempts to
run other programs.  For example, I would be using a vmware session, and
switch windows to an xterm and type 'su'.  The machine slowly start to
hang, the 'su' would be first, followed by the window manager and then
everything else.  Vmware seems to be fine as long as it never has to be
swapped out.

Another way to trigger it is to run more then one vmware session at a
time.  This rarely ever works for me.
