Generally speaking, I prefer to avoid introducing options unless
really necessary. In this particular case, it sounds like the most
convenient way of solving the problem is to have a convenience
variable. And it sounds like the only reason why Paul hasn't looked
at the implementation yet is due to lack of familiarity with this
code?

    % grep '"bpnum"' *.c
    breakpoint.c:  set_internalvar_integer (lookup_internalvar ("bpnum"), num);

So, I would think that adding something similar in
thread.c:switch_to_thread would do the job.
