	I think that performance improvement is significant(I don't
	think performance improved by my patch).  But my patch is the
	first implementation of kqueue/kevent support for TTY.
	In fact, I could find a bug.  I hope to commit my patch.  But
	by performance reason, my patch is not accepted, I have no
	problem.


	Hi ed!  Thanks for your fix.  I confirmed that my patch is
	good works.
