Many thanks Ian, spot on.

umount /dev/sda1

I copied a large volume of files into a new directory.  I'm not so sure that 
use% is an estimate, more of a determinate calculation that factors in more 
than just the other numbers that df gives, in order to appear superior to the 
hapless user.  I for one welcome our new number-crunching 
disk-space-up-our-sleeves overlords.  :)  On the other hand, adding the 
reserved amount to the df output sounds like a sensible improvement to consider.
