I think I was too hasty, there.  This is what should happen:

* The literal 18446744073709551615 gets parsed as the JS Number 18446744073709552000.
* 18446744073709552000 gets run through the "convert JS value to IDL unsigned long long" http://dev.w3.org/2006/webapi/WebIDL/#es-unsigned-long-long, which in step 5 would do 18446744073709552000 mod 18446744073709551616 == 384.

So 384 is the actual IDL unsigned long long value that gets used, and which should be returned as the JS Number 384 when getting .loaded.
