The garbage collector manually manages its internal memory structures.  In  
general, there is no need to collect any GC memory, because it doesn't  
allocate any unless requested to do so.  When it does, any metadata lives  
as long as the memory lives.  In the cases where memory is returned to the  
OS (via GC.minimize), the metadata goes along with it.
