[virtmach] garbage collection

[thaddaeus.frogley@creaturelabs.com]

Hi all,

Anyone got any links and / or advice on garbage collection ? :)

Or just want to discuss it ... 

I'm thinking, VM (obviously), single threaded environment, indexes into a
repository containing polymorphic objects act as handles and are stored on
an untyped stack.  

The way I see it, if 'n' isn't on the untyped stack then no references to
object 'n' exist, then it can be removed from the polymorphic repository.

(I don't actually think I'm going to need this, I interested in ways it
could be done if I did...)
