I wrote a patch to do #2 (pre-allocate vectors of the correct size).  I am not sure I guessed the sizes 100% correctly, as I still see a few fastMalloc's where I wouldn't expect them, but it was a small win.

I don't think #2 is worth doing.  #1 is where the real money is.

It's also unclear to me how exactly the OverlayMap is used -- if it's written to more than it's read from, for instance.  An OverlayMap which is smart enough to normally use a Vector<IntRect> and only convert to a Region when necessary might be possible and might be a bigger win even than making Region::union fast. :)
