Here is a patch to 'screen' to allow display of load averages on a
Sun system (tested under Sun-3 UNIX Release 3.3 and Sun-4 SunOS 3.2).
Unlike most (all?) other BSD-type systems, Sun keeps the load average
in /vmunix as 3 scaled integers, not 3 doubles-precision floats.  The
conversion is simple and standard.

(Betcha this .signature appears twice!)
