No no, they wouldn't be replicated.  Each task would have its very own
data dictionary with its own variables.  Immutable data like code and
constants could be shared, but even then, that sharing wouldn't be
apparent to the application code.

There are actually a couple of applications I'm considering this for.
One is a flashlight (toykeeper.net/anduril) using a small MCU.  The
other is a battery controller, whose CPU is probably larger, but I don't
know at the moment what it is.  Both applications are written in C (not
by me) and the idea is to extend them with a small Forth.
