My idea would eliminate that work around and make it automatic.  Who 
actually waits to constantly look at their disk usage and try and 
figure out if they have enough space left on their 512 meg partition 
when they have 200 gigs free on another?  I think most people find out 
they're low on space when they run out trying to do something on that
