Boyd's right on this one: vfork was done for the 780.
The 750, being a different implementation, had different
MMU peculiarities, and there were some difficulties getting
COW to work on it.  I remember John Reiser struggling with
it for 32V.  I believe he eventually conquered it, but it wasn't
easy.
