It's already LGPL'd, so anyone is free to use it. It's in 68K assembly, but
it is a direct implementation of the mark-and-sweep collector described in
the ETH Technical Notes. I do think its efficient, especially when there
isn't much garbage to collect. Informal observations show the mark phase is
very fast, with most of the time being spent in the sweep phase returning
memory blocks to the system.
