[Bug gdb/9747] New: Quit and "(running)" bug

["muller at ics dot u-strasbg dot fr" <sourceware-bugzilla@sourceware.org>]

I have troubles with CVS HEAD gdb on cygwin, related to the "(running)" state.
But I don't think that this problem is windows specific...


  Easiest way to reproduce these problems is to:
Run gdb with itself:
./gdb ./gdb
$ ./gdb ./gdb

  The problem is the set_running function introduced for the non-stop mode probably:
the fact on Quitting at the --Type <return> question bypasses the
 set_running(..,0)
(I discovered that by adding an printout on each set_running call) and thus
leaves gdb beleaaving that the threads are running while non-stop mode is not
even implemented yet on cygwin native gdb!

  This needs a fix!
