Subject: [PATCH] [project @ 2003-02-04 11:55:54 by simonmar] Add support for
 using vfork, which I apparently removed when this file was
 moved over from ghc/lib/std/cbits.  Using vfork on Linux
 makes quite a big difference - eg. when building GHC.Base
 with -split-objs , I saw a 2.5s reduction in system time.
