 Sigh.  Hold off a wee bit please.
 
 That test I sent eariler was 100% reproducible and your patch fixed
 that case.  But I found someone else who was having similar problems
 and he reports he can still get stuck processes.  I'll spend some
 time trying to reproduce his case to see if I can reliably make
 it happen somehow.  He said with this patch it does change what
 happens - the process being debugged does notice that it gets hit
 with a sighup when he exits gdb but the process being debugged
 doesn't die.
