I took a look through all the other proceed() calls and couldn't see
anything else that might want to share this code, so my preference would
be to leave things as I initially proposed.  I like the simpler each
function has one clear goal, rather than overloading proceed_all_threads
with multiple meanings ("all threads", or "all threads in inferior").
Especially not a fan of default arguments for cases like this (or in
general much).

That said, if you consider this a blocker to merging this patch then I
don't feel that strongly against it so would make the change to get this
fix merged.

Just let me know.

Thanks,
Andrew
