Why does it have to be a separate API? Isn't the edge-triggered
mode just a matter of passing EPOLLET into register?

If so, I would advise against having two sets of functions,
although having two sets of constants is propably fine.
I would just provide a second constructor, select.epoll(),
which guarantees that epoll is used as the implementation
strategy (i.e. it would raise OSError if the kernel doesn't
support epoll_create).
