No, if you'll look at my original figures that I posted, you'll see what that
exactly says WHY the machine you are on should have vfork()!

This above data says flatly that your machine does not have vfork(). If
it did have vfork(), I suggest that based on my figures you could probably
do about 1400 vfork()'s per second.

Geez, a sun3/50 can beat your vfork() behaviour! HAHAHAHAHA! I should
compare it to an 11/750, but I don't wish to brave that much slowness right
now -- it just might beat you though.
 <tdr.
