I've had it happen on several versions, 2.2.0-pre5 and 2.1.127 (I think).
As someone pointed out earlier, it's not just a matter of kill -9ing
processes on that mount point, I tried that and it worked fine. I haven't
had it happen in a while, but it always happen when I test this one
particular piece of code... I just can't remember what piece it is. When
it happens again I'll post all the details I can. I think it may have even
happened on a 2.0.x now that I think about it.
