Some of the badly written programs keep files open and expecting GC to close them, especially code written before with statement has introduced.

I have seen them in some web frameworks and many other modules.

They open file , process them and just ignore closing, causing pypy to fail to work. Fixing them is just a matter of using with statement or manually closing .

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

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.
