Perhaps we have different ideas of what a "functional fork()" is.  On
UNIX, fork() creates a copy of the running process.  Since DOS is not
a multitasking OS, I don't see how this could be done for DJGPP.

It is entirely possible to accomplish under DOS. Multitasking can be done
outside of the OS, as packages such as CTask indicate. All you would have
to do is save the status vector in go32 and swap in the new process. This
requires a large amount of programming, ie a procedure to stave the current
status, a timer to control when processes are switched in and out, etc. etc.

You seem to forget that an OS is not magic, just a piece of software, and that
just about anything that can be accomplished in an OS can be accomplished
in a seperate program as well.
