I agree in principle -- much better the bugs we know than the ones we
don't. But, IIUC, the patch we'd be reverting is from March, 2006,
which means that there's potentially a lot more that depends on it. In
that sense, I don't even feel confident that reverting the change is a
conservative move, likely to lead to less optimal code, but not wrong
code. Are you? (That's a serious question; not a rhetorical one.)
