The changes to allow the frame to unwind itself as part of 6919934 caused every compile to have at least one exception handler. This resulted in roughly a 10% compile speed hit because of the extra work and allocation required by that. We should fix this either by backing it out or by finding a way to do the same thing without the extra overhead.
