Beta-testing for BackGrounder has turned up a serious defect in a Big
Board I double-density 8" bios (19 June 83).  It handles sector
deblocking very inefficiently, resulting in a 20-fold slowdown in
effective disk i/o when reading then writing the same random records!

Does someone have a more recent version?  Is the problem present
in the BB II bioses also (the code contains lots of calls to "flush").
Is the author reachable?
