How does this logic work when the instruction emulated is an STI or MOV

sets set to reflect the *blocking* operation?
mov ss is a non-issue, since it is executed natively.
Except in big real mode (needs emulate_invalid_guest_state = 1).
As for sti, I'm not sure. I see code for emulating sti, but in my testings,
this code was never ever touched, under a number of different scenarios.
Avi, can you clarify if sti can be in fact emulated, and under which
circunstamces?
big real mode only.
