I've added a thread doing 'for (;;) pause();', but unfortunately that
doesn't seem to do the trick. Do I need to go into Cygwin internals and
wait directly on the Win32 event(s) used for signals?
sigwait() will probably work better than pause.
That indeed works, thank you very much! I didn't know that function,
very handy. With that and threads, signal handlers with all their
vagaries aren't really needed anymore, are they?
And speaking of threads, does it make a difference whether one uses
Pthreads or Win32 threads? I mean apart from portability and the small
overhead Pthreads presumably incur.
MinTTY's got three such little helper threads hanging about now, doing
waitpid() on the child process, read() on the child pty, and the
abovementioned sigwait(). Would there be any point in trying to
consolidate them into a single sigwait() process, using SIGCHLD and
asynchronous reads?
