Yes, you can. That's how other bindings work too: everything loops around a 
central select / pselect / poll / epoll call.

You need to set watch and timeout functions in the connection, as well as the 
thread wakeup one. Then the connection will call your callbacks whenever it 
has to changes to your pselect loop.

Then you tell the connection to handle its timeouts as well as reading and 
writing. After you've given it new data to handle, check the connection's 
dispatcher status and dispatch.
