check if select.poll is present, switch to select.select if not

[kkurian]

select.poll() is not supported by all platforms and so "most libraries check if select.poll() is present and switch to select.select() if it's not." [1]

The popular gevent library depends upon the above behavior and removes select.poll().

Request: In order to support gevent, check if select.poll is present and switch to select.select if it is not.

I doubt I will have the time to implement it any time soon but if well abstracted il would be nice indeed.

@seb-m Please let me know if #117 meets your requirements.

@kkurian As this repository seems unmaintained we've created a fork[1](note: it requires Python 3.5+), the fork fixes the issue you describe here.
