RE: async operation

["Newman, Mark (N-Superior Technical Resource Inc)" <mark dot newman at lmco dot com>]

IMHO async is not an invention of the client but the manner in which gdb
controls the client. ;-)

I am attaching a gdb output with remote_debug set.  In this instance the
sequence

> interrupt
> cont &

worked once but did not work the second time.

However I am going to suspend asking what happened since my version of
GDB has been modified to accept commands on a socket rather than
directly from the keyboard by substituting the FD for the socket for
stdin.  I added (among other things) the following to main:

  	 gdb_stdout = marks_stdout;
	 gdb_stderr = marks_stdout;
       dr_fd = fdopen(dr_in,"rw" );
       instream = dr_fd;
       reinitialize_event_loop ();

where dr_in is a socket.  Among other things I had to add a reinit to
the event loop to update rl_instream.  These changes will not go into
gdb before they are fully discussed on this forum.

It may be my changes that are causing the problem.
