# Are you sure this is a bug in the driver?  Often - I see this with tar,

It seems to happen in dd as well.  This indicates to me that the extra EOF
marker is exactly that (extra), and since the driver handles the EOF writing
(the programs should NOT explicitly be writing EOF marks unless they're
doing something extra special), that classifies it to me as a (dr. evil
impression -- don't forget the finger-quotes!) "DRIVER BUG".
