Actually, that's wrong. What it does is allocate everything on the
stack by rewriting the program so that it keeps track of the stack
frame in which a value must be placed so that the lifetime of the
stack frame corresponds with the lifetime of the value. Data
structures that can grow arbitrarily large spill over into the heap
but they are still freed in a stack-like manner. Like Apache's pools
there is a potential for unpleasant memory leeks so it would probably
benefit from a garbage collector for on-heap regions, but it seems to
do well enough without one.
