The latest fixes stop bash consuming a cpu, but typing `^Z'
can't wake up its prompt.

I tried tracking down this and found the following problem, but
I couldn't fix it.

In that case, SIGTSTP caused by bash wakes the "sig" thread in
the win32 process creating the notepad process.  This process
can't properly handle the signal because sync_proc_subproc has
been released by proc_terminate() in spawn_guts().

In the concrete, proc_subproc() can't clean waiting threads so
the "main" thread in the process can't start to execute the
signal handler.

Is my understandings right?
