Re: Another UVM wire page count underflow panic

[Robert Elz <kre%munnari.OZ.AU@localhost>]

Actually, on a bit more reflection, perhaps the best way forward
is to work out a better method of implementing the shm() stuff
puerly out of uvm facilities (with minimal, less than is there now,
extra data structs) - so shmctl(SHM_LOCK) is just mlock() but perhaps
with an extra parameter to the underying function which does the work
to indicate the semantics.

Anyway, later...
