Even this is not enough. PC floppy hardware doesn't have a "lock media"
function, so you can get the same panic by changing a floppy for a
write-protected one while it is mounted.  

I suspect that this hardware-induced inability to usefully cover all the bases,
along with some more fundamental structural changes that are happening in
-CURRENT, are why this hasn't been solved more gracefully for -STABLE yet.

Until then: "Don't do that!"
