No problem. I looked before I leaped in this case. I had
time to do so because of the on-going build.

While I do not have access right now, I do sometimes have
access to a couple of 2-processor PowerMac G4s, but they are
desktop machines. For all I know they might also have the
tbr mis-match problems with th->th_offset_count in binputime
as well. So at some point I may be able to test such a
context.
