[LMH]Exploiter progress

[Nyef]

Hello all.

I've just pushed a new tarball to:
http://www.dridus.com/~nyef/lispm/exploiter/exploiter-9c0822.tgz

This release contains a couple new miscop handlers, and gets to the first
invocation of %PAGE-STATUS (from deq-element in micronet/queue.lisp),
somewhere under GET-BOOTED-LOAD-BAND-INFO. The call to %PAGE-STATUS is
from an inlined call to wired-p (from memory-management/page-defs.lisp).
This instruction wants to return the first word of the PHT entry for an
address. Fortunately, only the low 25 bits of this word appear to be used
(implying that it is a FIXNUM).  Unfortunately, exploiter does not yet
implement the PHT, so there is no data to return. The obvious two options
are to emulate the PHT or to fake it. Ideas for how best to fake it will
be entertained for the next week.

All programming can be viewed as an exercise.
