You might want to consider looking into using the LWT library? (http://ocsigen.org/lwt/ http://ocsigen.org/lwt/) It's fairly mature, has a bunch of standard libraries already wrapped up into continuation-passing / callback style (I believe this includes libev, a cousin to libevent) and has a nice syntax extension too that can save the typing required to explicitly wrap things into callbacks.
