Re: either me or GC sux badly (GC don't reuse free memory)

It's been a while since I Dded this, but I think the GC will 
effectively call minimize after collecting, so any collected 
large allocations should be returned to the OS. Allocations 
larger than 4K get their own dedicated pool, so fragmentation 
shouldn't come into play here.
