Ah right, I missed that point. That makes it difficult to find an application that would break :-) One problem is that epoll allocates another file handle, when poll does not; the other problem could exist when the EPOLL constants differ in value from the POLL constants (which isn't the case on Linux), and then somebody uses numeric values instead of symbolic ones for register(). That said, I would be in favour of having select.poll "silently" use epoll where available. Of course, it would be good if a "cheap" run-time test could be made whether epoll is available at run-time (although just waiting for ENOSYS from epoll_create is probably cheap enough). Also, it would be good if the application could find out it is using epoll; for example, epollObject could expose a fileno member.
