> Maybe we should add one?

I don't think that we need to add an *builtin* exception for every single possible errno. On Linux with Python 3.7, I count 133 different error numbers:

>>> len([name for name in dir(errno) if name.startswith("E")])
133

PEP 3151 explains the rationale for added OSError subclasses.

I think that we should focus on the most common ones, especially the ones which are available on all platforms.

I have no opinion about "errno 39 (Directory not empty)". Is it a "common" error?
