Huh..that's odd. TAO state in their docs for vpcc that fork() will
never be supported properly.

Include externals compatible with POSIX standards but do not include
any Elate-specific externals which may be defined in the standard
includes.
Provided to stop any name clashes when porting. Some Posix
facilities e.g.
fork(), will never be supplied in a compatible way under Elate.
I've also noticed that fcntl() and lockf() aren't POSIX either. Some
ported code needs work when dealing with these.
