I'm not sure if addresses your needs or not, buy there's a PhD thesis you
might want to check out:  "Scheduling Garbage Collection in Embedded
Systems" by Roger Henriksson.  It's available at
http://www.cs.lth.se/~roger/thesis.html .  I've been out of touch with
Roger for over a year, but it looks like he's still doing research into
garbage collection techniques for doing real-time in Java.  He's a professor
with the University of Lund.

I hope this helps,
