Adding tail-recursion optimization to a Forth is such a simplistic
and obviously beneficial thing, I'm not surprised that other people
have implemented such a thing, also.  What's particularly interesting
about Chuck's tail-recursion optimization is that it's built into
the interpreter, using intelligence from the state machine in its
core.  See Sean's Flux code for information.  It's simple and fast
and good.
