After speaking with Stefano we've decided that since this didn't
actually address the SMP issue you were chasing and since we are now so
close to the 4.3 release (this is partly my fault for being tardy with
applying the patch, sorry) we will hold off on this change until 4.4
development opens. Shouldn't be long now before we branch...
