It's hard to diagnose without seeing all the code, but it
sounds like you might be running out of memory.  Are you
printing a lot of output that could be bloating the screen buffer ?
Also, you might want to check that all the handles you open
are closed properly.  The ones created as PyHANDLEs will
be closed automatically, but plain int handles won't be.
