I rerun the experiment with and without this commit. The numbers are the same as before except that there is no difference in NumNoUnwind. I don't know if I used a different baseline or if there was another problem (e.g., concurrency related) but I don't think this patch does affect the NumNoUnwind number at all.

Btw. I only report statistics that changed more than 1% as there seem to be some minimal variations all the time.
