No, that says "round up", so it does mean that the requested timeout
should be the minimum amount slept. tvtohz() does this. Really odd
that the socket code is using its own version of this rather than
tvtohz().
Oh, I bet this just predates tvtohz(). Interesting that it keeps getting
bug fixes in its history that simply using tvtohz() would have solved.
Try this:
