But a user is within her rights to do that.  Creating a program that
loads both of these libraries is allowed -- distributing it in Debian is
not.

Distributing a package that *does* this is in violation of the GPL; that
is, we cannot legally distribute a python script that calls both 'import
socket' and 'import readline'.  But we allow users to do many things
that we ourselves cannot: a user is free to create such a script on his
local machine, and he is free to call 'import socket' from the python
IDE.
