Changes since version 0.11.8:

* fsevents: share FSEventStream between multiple FS watchers, which
  removes a limit on the maximum number of file watchers that can be
  created on OS X. (Fedor Indutny)

* process: the `exit_status` parameter for a uv_process_t's exit
  callback now is an int64_t, and no longer an int. (Bert Belder)

* process: make uv_spawn() return some types of errors immediately on
  windows, instead of passing the error code the the exit callback. This
  brings it on par with libuv's behavior on unix. (Bert Belder)
