Is the directory busy?
That is is it the pwd of some process or have open files?
If it's not then it will be umounted when it times out, after 1 minute
in this case. Then if some smart application scans directory trees when
it sees mount or umount activity then it will be mounted again. We've
seen this with older versions of hald.
The best way to find out what is causing this is to enable debug logging
on a test machine and check what pid is causing mount activity.
