Ops, sent before ready

After a little more thought I think that a more likely explanation
of the results on Steve's 8 core is that since it is a dual cpu machine
(but with 4 cores/cpu), the cost of locking and synchronization in the
VM is so much higher than in a 1-cpu many core machine.

So as the size of the files increase the relative cost of the locking
overhead decreases and we get some great results on really
large files.
