Do you have any performance measurements with the option enabled at this point?


Nope.  I'm hoping for others to provide those.  And ideally help with
performance profiling and tuning.

I think you should at least try for initial numbers on whatever machine you're using. Try compiling libstdc++, say, at least. If your patches aren't a performance win, they're not going to be terribly compelling; if they are a win, as expected, then that will make them much more compelling.

Even if this patch doesn't show an immediate performance win, isn't simplicity and the possibility of future improvements an argument in its favor?
