Possible chances to take advantage of libuv stability

Use of libuv polling for the more hardware orientated modules is being seen.

Use is being made of libuv to detect events on a file descriptor in existing stable modules. Some of the features that libuv provide could be exposed via NAPI or use of libuv could be allowed in order to avoid complex changes to some modules.

modules looked at that support these cases

github repo	description	npm wkly downloads thousands
node-serialport	arduino serial port driver allowing educational and hoby	23
node-raw-socket	module used by net-ping for JS ping utilities	433

Code fragement example

void Poller::poll(int events) {
  this->events = this->events | events;
  int status = uv_poll_start(poll_handle, events, Poller::onData);
  if (0 != status) {
    ...
    return;
  }
}

I would love to see this. uv_poll_t is very useful and not very complex.

@cjihrig in the event of a libuv-2.0 release, is there danger of the polling API suffering an ABI break?

Not that I'm aware of, but I'm going to ping @bnoordhuis just in case.
