This is an absolutely horrible thing for a user program to do. The vfork() call was never intended to allow you to update the parent's address space and as the man page states, should never be used in such a way. Besides, FreeBSD doesn't have an implementation that supports this anyway :) If tcsh (I think it's actually csh) *really* wants to update some of the parents address space on FreeBSD, it should use rfork() instead IMO.
