If the code were re-entrant, you could simply copy stacks and global data
areas... which leaves one problem: 

	There is no way on the amiga to duplicate generic file handles.

So much for fork.  Besides, we are having enough trouble with a simple
fexec.	*really* is there anybody at all over at amiga who knows how
to get BCPL programs to work?

One thing I would like to do is startup a CLI window WITH a command (but
still interactive).  (E.G. I want to startup a CLI window with my SHELL
in it)

Update On Shell: Sorry folks, no go with getting it to run from the
workbench.
