I want to do an event emitter that gets events from libudev.

udev_monitor_get_fd gives me a file descriptor that I'd need to poll, and
once the descriptor wakes up I'd need to call udev_monitor_receive_device
to retrieve the event so I can emit it.

Am I able to do this with node.js and libuv or do I need to pack that
monitor into it's own thread?

If you're targeting node 0.8.0 or later, you can use uv_poll:
