But my guess would be you might solve the problem by updating FontForge.
Apr. 2008 is pretty early in the history of FF Python scripting, and I
wouldn't be surprised if FF was using memory inefficiently at that time.
And, as I've said, Python 2.5.2 is working fine for me.
And it would be easier, I suspect, to update FF than Python, which has
so many dependencies in any Linux system. So that's a place to try.
