Can you hit ^Z and escape to the shell?  Can you switch to another 
virtual console and see what's going on?  What does the program do?

Yes of course people care about Python bugs, but if you want
personalized phone consulting you'll probably have to pay for it.
If you're willing to do that, I'm sure plenty of us here are available.

If worse comes to worse you may have to run Python under gdb.  Is
your program using multiple threads?
