    sys/i386/i386        exception.s 
  Log:
  Set p->p_switchtime to switchtime instead of to the current time in
  fork_trampoline() if switchtime is valid.  This fixes not accounting
  for the time between the previous context switch and and the current
  time (when the forked child starts up here) in most cases - the time
  is now counted in the child's runtime.  I think it actually fixes
  all cases, and switchtime is always valid here, since there must have
  been a context switch just before the forked child starts up.  Some
  code should be removed if this is correct.  The check that switchtime
  is valid sometimes gives a false negative because the check isn't
  correct until the after the first context switch after the system
  has been up for >= 1 second.
