It doesn't really have to be garbage collection. Python uses
reference-counting, and IDL could easily do the same kind of thing,
with extremely low overhead. Internal to IDL, what is needed is one
additional integer for each heap variable and three extra instructions
per pointer assignment.

Garbage collection might still be useful for when cycles occur.
