Ask Unix Co-Creator Rob Pike
Today we return to our Slashdot interview roots with a "Call for questions" for Rob "Commander" Pike, who has been involved in the development of many modern programming concepts, GUI advances, character sets, and operating systems. We'll email 10 - 12 of the highest-moderated questions to Rob and post his answers as soon as he gets them back to us.
Jeez, someone, click on the fuckin link in the post with his name. He's not a Unix co-creator. He worked a lot on Plan 9, and wrote a bitmap windowing system for Unix. But he's not a Unix co-creator. The creators of Unix are Dennis Ritchie and Ken Thompson.
The operating systems link goes to encyclopedia.thefreedictionary.com, which is a scam-site that steals articles from other sites, in this case from Wikipedia. The only thing they've added are ads. The original can be found at http://en.wikipedia.org/wiki/Plan_9
I think that he and the Bell Labs folks already answered those questions over 10 years ago:

Actually, the refuse to umount if there are users in the mount is part of the POSIX or SUS specifications.
Linux does not have a problem with it. That's why it has the -l option.
-l Lazy unmount. Detach the filesystem from the filesystem hierarchy now, and cleanup all references to the filesystem as soon as it is not busy anymore. (Requires kernel 2.4.11 or later.)
There: Something at a specific location.
Their: Owned by someone.
