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).
