I have no idea how to get this right for the pipe case.  Maybe someone
else does.

I don't think "write" will do it; you need something more complicated.
Maybe I'm wrong and writing the interrupt character will do it.

GDB expects, today, to have a console.  It expects C-c to go to the
foreground process group on that console.  It arranges to be the
foreground process when GDB is stopped, and for the inferior to be in
the foreground when it is running.

This may not be the most useful behavior for your case.
