I'd take a look at 

Memory management with explicit regions, David Gay, Alex Aiken ACM SIGPLAN
    Notices Vol. 33, No. 5 (May 1998), Pages 313-323 in: PLDI
    '98. Proceedings of the ACM SIGPLAN '98 conference on Programming
    language design and implementation, pages 313-323

not exaclty a GC alogrithm, but I think you could adapt their techniques so
you can mangage clumps of objects in an interesting way.
