With this patch, instances of pdb.Pdb can read and
write from arbitrary file objects. It is based on
similar changes that have been made to cmd.py. It
basically consists of replacing print statement with
calls to self.stdout.write.

So it is possible for example to control the debugger
from another terminal to debug curses-based
applications or CGI scripts.

I can provide a basic client/server debugger.

This patch has been tested on Mandrake Linux 9.1 with
the current CVS version.
