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.)
