    Description

      SelectableChannel.register is specified to synchronize on the selector's key set and therefore may block if invoked while a selection operation is in progress.

      This issue tracks relaxing this so that register can be invoked without waiting for a selection operation to complete. New registrations or changes to the key's interest set can take effect at the next selection operation.
