Comment (by pdimov):

 Replying to [comment:9 aaron.riekenberg@…]:
 > I experimented with lwsync.  It was slightly faster than sync in my
 tests (around 300 nanoseconds).  lwsync does not enforce ordering of
 stores followed by loads
 (http://www.ibm.com/developerworks/systems/articles/powerpc.html).

 Yes, I know what lwsync does. You don't need sync here.
