[BUG] Quit and "(running)" problem

["Pierre Muller" <muller@ics.u-strasbg.fr>]

  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!
