No, I didn't see the module. To be honest I didn't look at the Python
Package Index but used Google to search for epoll wrappers. I found the
wrapper in Twisted on my disk and two other wrappers. One was written in
pure C and the other one used ctypes.

Your wrapper is a good implementation. I even found an inconvenience in
my implementation when I studied your code. My wrapper raised an
exception when a closed fd was removed with EPOLL_CTL_DEL.

I agree with Gregory on that part of your answer.
