Several people, said the man pages are broken:

	This is a  bug in the man page. It  is so poorly
	worded that  it is broken. "maximum"  here means
	"minimum" in  the case  where no  selected event
	occurs.

		Daniel Eischen on Jan 23:
	You have  to guarantee  that the actual  time is
	greater  than or  equal  to the  amount of  time
	specified.

		Warner Losh on Jan 23:

	Somewhere in the archives  have a pointer to the
	unified unix spec for select. Might want to look
	for  it. A  useful regular  expression might  be
	http://www.*/select.*.

This is becoming ridiculous. Somehow, I  get a feeling a bunch of people
manage  to agree  with  each other  on a  subject  they express  exactly
opposite opinions.
