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

PyPy uses a different garbage collection strategy, and unlike CPython,

objects are not deallocated as soon as the variable goes out of scope:

FWIW, Java has a very similar behavior.

Never heard of it.

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.
