------- Additional Comments from Geoffrey Garen <ggaren at apple.com>
This patch eschews an "Is this stream valid?" check in favor of a "Does this
stream belong to the plug-in using it?" check. So it avoids introducing a
function that can create subtle bugs by promising to do more than it actually
can, even though It doesn't do much more in the way of guarding against bad
behavior.
