Calling this garbage collection is watering-down the term to near 
uselessness. This is just manual memory management. I haven't 
read the code, but from your description it sounds exactly like a 
bump allocator and a tweaked general purpose allocator which can 
reuse allocated memory regions when heap fragmentation becomes an 
issue.

These days, these technique should be unremarkable. I have no 
doubt that this was innovative in '93. But 30 years later, 
creating a bump allocator for memory which doesn't change much 
after init with a known lifetime of use should be common practice 
for programmers, especially when most PCs have > 8gb of RAM.
