Yeah, trusting the GC - reading the original author's comments on it:

> Mind you, the whole heap code really needs a rewrite to reduce per-object memory overhead, and to remove the need for the binary tree of allocations. Not really thinking of a generational GC, that would probably add to much code. This was something I vaguely intended to do, but never got around to. The current heap code was just the simplest thing to get GC working quickly. The very initial implementation did no GC at all. It was beautifully fast, but ran out of memory rather too quickly.
