Currently we reenter guest mode after each iteration of string
instruction for all instruction but ins/outs.
E.g., is there no chance that during the repetitions, in the middle of the
repetitions, page faults occur? If it can, without entering the guest, can
we handle it?
-- I lack some basic assumptions?
If page fault occurs we inject it to the guest.
Oh, I maight fail to tell what I worried about.
Opposite, I mean, I worried about NOT reentering the guest case.
I know that current implementation with reentrance is OK.
To inject a page fault without reentering the guest, we need to add
some more hacks to the emulator IIUC.
Thanks,
