Under the POSIX environment.

The problem with fork() outside of a narrowly defined environment like POSIX 
is exactly what part of the process needs to be replicated - and the biggest 
problem is DCL and IO.  I have argued for years that fork() in a VMS 
environment doesn't need to be general - that the solution used by POSIX is 
pretty close to being the correct general solution...  fork only makes sense 
in a C application being ported to VMS - and running it should simply create 
a POSIX environment on-the-fly (or run from the POSIX shell).
