That makes senses.  The good news is that this can be done 
incrementally, unlike the present patch series, which required changing 
the signature of methods used all over the place.  At least one 
implentation of target_fetch/store_registers (bsd-uthread) needs to read 
or write memory, and therefore will need to save/restore inferior_ptid.  
But the big majority of them won't need to do it.

That sounds right.  Thanks for the tips!
