Could you explain about closed file objects (do you mean open file descriptors)?
I've never heard about this restriction before.

Here are things PyPy Can help:

- If it is Pure Python
- If CExtensions are with CFFI
- If file objects (if any) are closed 

PyPy will work fine and you can expect average 7x performance gain , up to 20-30x.
