Does Twisted have additional tests? I agree that the tests are too light
weighted but I don't have spare time to write more tests. I may have
more time in a few days after xmas.

I've seen the limitation in an example somewhere. I've read the specs
several times and I think you are right. I now use FD_SETSIZE as
sizehint for epoll() but I don't limit the amount of fds any more.

I'm using FreeBSD to test the kqueue interface. I can't tell if it's
working on Mac OS X. I've put the NETDEV related macros in an ifdef block.

The new patch replaces the FD_SETSIZE limitation and adds a richcompare
slot to kevent. Do we need an alternative constructor which creates an
epoll and kqueue object from a given fd?
