Well, "unwise" is relativated if your "change media
tool" really locks the device, flushes the caches, unlocks and ejects
the media. You insert a new media in the drive. Lock media, remount
filesystem, unlock device.

By locking the device, it is sure no other application has still an open
handle to files on that media.

This should work. But I haven't got LOCKDRV's source code. Neither is my
"FLT"-knowledge sufficent to alternate it's behaviour in the
intended way :)
