Well, it does matter if you have to halt 8-32 threads when 
scanning all memory that may contain pointers.  If that is the 
only option then automatic reference counting with optimization 
is a better choice, but I think a mix of task-local GC og global 
RC (with optimization) is a reasonable trade-off.
