garbage collection

[Steve Dekorte]

I think I remember reading that Self uses a generational copying garbage 
collector. Is that right? If so, I'm curious about why that approach was 
taken instead of something like an incremental tri-color collector.

A generational collector would avoid the frequent pauses of a mark and 
sweep collector but would still have  infrequent pauses which (I would 
think) would be a problem for a interactive system.

Cheers,
Steve
