This function is to provide the function "usleep" which is
available on some but not all platforms.  My usleep manual page 
says:

       The  usleep()  function  suspends execution of the calling
       process for usec microseconds.  The sleep may  be  length-
       ened  slightly by any system activity or by the time spent
       processing the call.

I think it isn't needed.  (Maybe it once was, or someone just 
copied headers from somewhere else.)

It seems to be needed for select() (networking stuff, also to
fake usleep if necessary), maybe other stuff as well.
