Idempotent: Currently Gecko's parser and the URL Standard's parser are

Standard to fail parsing empty host names. I'll have to research if
there's other cases that are not idempotent.
I don't actually know what this means. Are you saying that
"http://@/mozilla.org/"; sometimes resolves to one URI and sometimes another?
function makeURI(str) ioSvc.newURI(str, null, null)
makeURI("http://@/mozilla.org/";).spec -> http:///mozilla.org/
makeURI("http:///mozilla.org/";).spec -> http://mozilla.org/
In other words,
makeURI(makeURI(str).spec).spec does not always return "str".

nitpicking, that's not "not idempotent". It's not round-tripping, but it
looks like it's idempotent.
