        It's really rather smaller than this; a better proxy is:

$ git grep 'throw  *[^(]' | wc -l
16279

        Nice breakdown :-)

        So of course the 16k number of throws seems huge, but next to our:

$ find -name '*.[ch]*' | xargs grep ';' | wc -l
5600685

        it is 0.3% of our ';' lines ;-)

        HTH,

                Michael.
