I'm not an expert of this - but if all the reason you want to do this are
memory concerns, AFAIK forking will only make a copy of those memory-pages
that are actually written to by the forked process - for efficiency
reasons.

And even if that wasn't the case: I think as long as you don't run into
memory-troubles, don't do it. Its complex, flaky and thus an unnecessary
source of failure.
