I noticed that I was not aligning the per-thread hazard pointer 
data-structures on separate cache-lines!!! This is not a bug, it is just a 
fairly major performance issue... You should probably re-download:

Aligning the per-thread SMR data-structures on separate cache-lines shaves 
off an average of 2 - 3 seconds of runtime from nearly all of my tests!

Sorry! :O
