fixes Windows build

[vinipsmaker]

The fixed error is:

src\with_read_timeout.rs:40:13: 40:19 error: unresolved import `select::fd_set`. Maybe a missing `extern crate select`? [E0432]
src\with_read_timeout.rs:40         use select::fd_set;
                                        ^~~~~~
src\with_read_timeout.rs:40:13: 40:19 help: run `rustc --explain E0432` to see a detailed explanation
error: aborting due to previous error

Okay, PR is ready for review now

Thank you! I opted to fix it in 534eb46 without splitting the select module to another file.

Thanks.

Hey @meqif, could you take a look at #10 please? Also, would you be interested in a PR to replace you platform-specific implementation of timeouts with Rust ones?
