Well, as I said, I've always worked on multitasked Forths. But we do not 
handle interrupts in task code. It's a little hard to explain here, but 
there's a whole consistent design concept involving the relationship 
between interrupts and task-level code.

We rarely use variables for a truly "temporary" result, that's what the 
data stack is for. User variables are allocated and managed conservatively.

No, space is allotted according to the overall design of the 
application, but the allocations are usually permanent. I'm not even 
sure what a "leak" means in the Forth context.

Yes, it's a very different programming style.
