	It was incorrectly asserted that the only way to determine
	whether a pipe was empty was to read it, that there was no
	way to time out the read or even terminate it.  None of
	these is true.  The number of characters in a pipe can be
	determined by fstat(II), alarm(II) can be used to time out
	the pipe, and any interrupt will terminate the read from
	the pipe.
