I oversimplified things a bit, actually. If a term is
small enough to fit in a VM register, then it can be
saved on the stack. Such terms include small integers
(fixnums) and atoms, and perhaps others.

(Allocating a fresh atom may cause memory management
activity elsewhere, though: in the atom table.)

This case is usually not considered when one speaks of
"stack allocating data", though. Usually the intention
is to stack allocate data that would normally end up
on the heap.

Best,
Thomas
