Yes. It should not be required to open the dir with delete-on-close, just because it's still open elsewhere. After all, the meaning of "setting the delete disposition" is not that the dir has to be deleted immediately if it's still in use.

More or less, yes. I'll check in my changes shortly.

Your changes work, I just tried the 20111023 snapshot. See the attached strace on Win7/64.

I also attached the simple testcase I'll submit to Novell. Please let me know if you think something is wrong with the testcase.
