I don't know about other people, but I suspect you're running into lock 
contention.  Try using a post 5.3 snapshot (something from RELENG_5) 
since alc@ has set debug.mpsafevm=1, which lets many calls to the VM 
run without GIANT, which I suspect is your problem and why the system 
usage is all over the place.  -sc
