I'm not able to follow this discussion completeley since I don't know the code 
in question so I need to ask: will probably_slow_mounted catch usb-mounted 
media, e.g. pendrives?  I noticed exactly this problem when inserting a 
pendrive in a Knoppix system:
1)insert pendrive
2)icon for e.g. sda1 appears on the desktop
3)clicking on the icon mounts the pendrive and opens a konq window
4)attempting to unmount the drive now always results in a busy notification.

The only way to unmount is by killing the appropriate kdeinit process (by 
checking lsof).  It may be redundant, but maybe the code for unmounting via 
kdesktop icons should include a check with lsof (or equivalent) to see if the 
path is only 'quietly' open in the cache.
