GC ought to be wholly independent of the ChucK thread that syncs the
music, since it is only about collecting unused memory. Suppose you
have a collecting GC that runs nicely in the sense that it does not
interrupt ChucK perfect timing. Then it could within that limitation
collect whenever it gets some time from the system to do it in its own
