It causes a 12% performance regression in a single testcase where KVM has a 150x performance regression. This says a lot about the relevance of the testcase. In any case, I have patches to avoid the regression. For 1.7 we can just revert the patches, for 1.8 we can apply this patch together with the optimizations that avoid introducing a regression.
