Hello John

	Sorry I was not able to send you the output over the weekend.
But, I just got done testing your VM changes you submitted on 5/29 and
things are getting better.  I was able with my 3D rendering engine able
to get 4 concurrent scenes rendering at the same time each using 15 megs
of VM space.  The results are:

panic: freeing held page, count=1, pindex=32(0x20)

_Debugger
_panic
_vm_page_free @ vm_page_free + 0x9b
_pmap_release @ _pmap_release + 0x13b
_vmspace_free @ _vmspace_free + 0x88
_cpu_wait @ _cpu_wait + 0x32
_wait1 @ _wait1 + 0x1c9
_wait4 @ _wait4 + 0x13
_syscall @ _syscall + 0x195

I hope this helps.  If you need any other information let me know.

Peace,
