Log Message:
Amplify comments per thread in source-changes-d about the previous
commit to this file: we must restore the PID value (that is, the
current address space ID) before touching memory, or the memory writes
might go to arbitrary wrong places or fault.

I'm not completely convinced this function (or other functions in this
file) are handling pipeline hazards safely, but I don't have
authoritative mips1 documentation any more so I'm not going to meddle.
