well, dang me, it actually worked.  there's no "trigger" mechanism yet
for the MMU to be requested to do the PTE lookup so i did it manually
(triggered the MMU manually) and it actually worked.

now the next phase is to attempt to do that job properly, by adding support
for the "OP_FETCH_FAILED" pseudo-instruction.
