Hi Tom,

Just one nit:

It probably doesn't matter because it's reassigned after sim_inferior_data,
is allocated, but this field should probably be initialized too, to be consistent
with the other fields.  ptid_t doesn't initialize its fields by default (to remain
a POD), so its initial content would be some garbage.

Otherwise, LGTM.
