GC is only a problem when it collects, which won't happen often 
if you don't leak that much. Used as a malloc/free, there is no 
reason for it to be slower than a malloc/free (a fast malloc 
already needs to be able to find the allocation metadata from 
free's argument effisciently, so you you got what you need for a 
GC already).
