Hi Andrew,
    I decided not to let the fact that I have never written any FS code
stand in the way of making suggestions :-) :-)
    Do you think it would be better to make the defragmentation part of
the normal operation of the FS rather than a seperate application. For
example, if you did a fragmentation check/fix on the last close of a file
you would know that coherency issues were not going to be important. It
might also give you some way to determine which files were important to
keep close together.
