In that case the device has been mounted R/O before, and if you don't remove it in the middle of a transaction, there is nothing the kernel might want to do with the physical device to unmount it (and even within a transfer, this ought to be caught by the driver). For that reason I had suggested to have a soft-R/O mode for removable devices, which together with a very short flush delay might allow such a device to be mounted R/O "nearly all the time" (tm) ;-) This is not a perfect solution, but it is similar to the way USB sticks are used with Windows/XP: Wait a second or two and remove it. While not perfect this covers the case of MP3 players or digicams that are mounted as USB storage devices, and many other cases. To make this a perfect solution is much harder, but even a simple implementation would be a big step forward.
