I wouldn't say that it adds nothing.  It does encapsulate the GC thread management code, and I think there is value in modularizing the code as opposed to having it all in one giant heap class.  That said, if it is adding complexity that is preventing your concurrent GC work, I won't object to its removal (especially since it may not be the best abstraction for breaking down the heap when you're done with the concurrent GC design).
