git  fetch  git://github.com/fdmanana/otp.git   external_size_2

Btw, why isn't the existing BIF erlang:external_size/1 documented anywhere?
I see it used in some OTP modules like dets.erl for e.g. I find this a
very useful function, as it's certainly more efficient then doing a
"byte_size(term_to_binary(Term))" call.
