Make read and write time outs configurable.

Since epoll is used in edge-triggered mode, if there's no socket activity, it'll block forever (even with a timeout value > 0). Haven't found any way around this that's not costly.

The timeout value is already configurable (I use the keep-alive timeout for connection timeouts).

Still worth investigating alternative solutions even if they're costly. Otherwise the server is too vulnerable to running out of sockets due to idle connections.
