  I doubt it's anything to do with 64 bit operations - I'm not seeing any
great number of unimplemented instruction traps.

  They are all pagefaults.

  A quick test during lunch shows this seems to happen after the fork()
when the shell is doing the exec().  It's almost like it's getting write
faults on a read-only page and the page is never getting set to writable
until later.  I think I'm going to add some instrumentation to trap.c
to capture the last N page faults and see what the PC and faulting VA
addresses are for them.
