I'd again say it is an issue of transparency.   Can the programmer, who 
may be trying very hard to keep CPU pipelines full and memory latencies 
low, anticipate when the garbage collector will want to do work, and 
what that will do to the stability of cache lines?  In a multithreaded 
garbage collector, the changes it makes won't necessarily be on allocations.
