change select with poll or epoll

select is used as the I/O multiplexing tool, can it be changed with poll or epoll

Hi,

originally this library was based on poll.
However, the problem was that Windows implementation of poll is... buggy.
So I changed to select which works perfectly fine.

One improvement would be to switch back to poll on unix and keep poll for windows platform, but I lack of time to do so at the moment. However PR are welcomed :)
