In my test, I am completing 100k lines worth of substitution in approximately 4 seconds. Your mileage may vary.

Can you give an example of the source you are parsing? Perhaps you can anchor your substitutions somewhere? Perhaps the code is "hanging" else where (i.e., have you tried print statements before and after this section to verify that it is where the "hanging" is occuring?)? How long does the program "hang"? Is it consuming CPU while it is "hung"?

Cheers,
Shendal
