linux-low.c: stop_all_processes vs longjmp snafu?

[Doug Evans]

linux-low.c:stop_all_processes is the only place that sets stopping_threads:

static void
stop_all_processes (void)
{
  stopping_threads = 1;
  for_each_inferior (&all_processes, send_sigstop);
  for_each_inferior (&all_processes, wait_for_sigstop);
  stopping_threads = 0;
}

and all functions that test stopping_threads can throw an error
(call longjmp).

I'm guessing fixing this is waiting on someone to remove stopping_threads,
right?
