I don't think so. First, you don't need a new garbage collector for the 
direction that I would take. Since the threads don't operate on the same 
object memory, no change to the collector is needed. And for shared 
state concurrency, simple solutions (like a gc request flag per thread 
which is checked on each send) can be used to ensure atomic operation of 
the collector.
