Another wonderful piece of Foundry technology lives on!  Thanks, IanT.
Note that on Unix this works by using a hacked tk_getOpenFile.  I
don't know if those hacks are in the Insight Tk.

My feeling is that what you really want is a way to be notified by the
gdb core when interesting state changes.  The GUI would run the "dir"
command, but would rely on this same notification to update the source
window cache.

You want this because then it doesn't matter how the state changes --
only that it has changed.

Whether this is done by hooking into the command interpreter in a
generic way, or more directly into the core (e.g. in this case in
directory_command()), I don't know.
