I'm writing specifically about moving a computation from one thread to
another. The issue is that a program can observe that it has been moved in
this manner (thread cells and things that use thread cells). Most programs
are not designed for this kind of movement to work; hopefully it will
immediately break horribly, but there is also the possibility it will just
do strange things in subtle ways.

Anyways, best of luck. I think you don't really need my advice.
