The parallel GC code is currently sitting dormant waiting for me to go back to 
it and figure out why it isn't performing very well.  Basically I saw little or 
no speedup regardless of how many CPUs I threw at it, which suggests that the 
bottleneck might be the memory system.  I tried a few things - prefetching, for 
example - without much success.

We know this is important, and it remains near the top of the priority list.  At 
this stage, I'd say it's unlikely we'll have parallel GC in 6.8, though.
