Sorry Steve, can't let this pass :-). Please name *one* case
where streams have value in Windows or Mac. And I'm not talking
about the case for EA's, these clearly have value (plus we already
have them :-).

I'm talking about a case where there is clear value in having
an openable/seekable stream on a file/directory.

I can't think of a *single* case where a stream adds more
utility than an EA used in the same case.

I don't want theoretical "well it would be nice if..",
I want clear "we couldn't have done it any other way"
kinds of things.
