OpenOptions.registerDefaultIdler

Whether the reactor should register the default (fd processing) idle handler

If this value is set to false, the poller is still opened. It's idle function would not be automatically called, however, so file operations might block indefinitely unless another mechanism (such as timer based) is put in place to call it periodically.

The non-registered idle handler can be manually triggered by calling poller.poll.
