2 seconds is too long. On other OSes (I'm talking about all the old
micros), it's quite usual to rip a disk out of a drive the moment the
light goes out, or even a bit sooner if you recognise that writing has
finished and it's simply timing out the motor.
It works with mtools, so user habits aren't going to adapt on this one
even if it makes sense -- it's not instinctive.

Hmm. I think everything should be invalidated in the style of revoke()
and something clever done with directories.

Yes it does... And you can't rely on the serial number because some
floppies (even MS-DOS ones) don't have one.

For those of us who want 50k less kernel and 50k more free user space, I
propose that the motor stays on until everything's written, writes are
scheduled as soon as the disk is idle (or soon after), and a disk change
unmounts the disk. :-)
