Mark thinks all my ideas will be really slow! Peasant! Grr!!! (Only
joking - best of friends really :-)

Seriously, stop and think about it. The defrag thread can run purely 
in idle time, ie it's at a REALLY LOW priority. OTOH, it sits there
invisibly sorting the disks out - so disk access is FAST and NICE!
What's more, it might find disk errors and things while it's at it,
and raise suitable alerts.
