No, it wouldn't. If you somehow need a "real" fork(), call a wizard and let
him do his tricks. Unfortunately, the only wizards left won't share their
knowledge, and the only way to get patches into the GeekGadgets CVS is to
ask upstream... Anyway, if you can't replace it, there's manual work to do.

I changed it because I realized that sometimes it is better to let a fork
fail than to accidently do an unjustified vfork that might just crash.

Yepp... just tell everybody :-)
