KDE: 'safely remove' does not safely remove

I think your problem is just that the Safely Remove process doesn't 
react well to handles being still open on the device, eg

  - stick a flash pen in and open it in Konqueror with the UI popup

  - in a konsole, cd /media/disk or whereever it was mounted (determine 
with mount)

  - then try to use the "Safely Remove" context menu on the desktop 
icon.  For me it removes the menu item from the context menu, but does 
nothing: the pens is still mounted and the icon remains present, there 
is no activity on the pen.

  - the Desktop icon representing the device does go away when the 
device is umounted by hand and pulled

Under these circumstances, eject says this immediately:

# eject /dev/sda1
umount: /media/disk: device is busy
umount: /media/disk: device is busy
eject: unmount of `/media/disk' failed

I separately tried to reproduce the proposed not flushing behaviour even 
after remounting without the sync option, but the icon correctly sat 
there until the whole 163MB test file was flushed to the pen, then 
disappeared.  Which is good!
