Just a that the t/perf/*rebase* numbers look much better with this. I don't have these in front of me anymore, but over 10 runs with -O3 one of those long-runnings test was 30% faster.

Another one (rebase -i) went from 0.02 to 0.01 sec, with that short amount of time I wonder (but didn't dig) if the test itself is broken...
