Gregg is heading along the right lines so more generally:



When this quota is reached what would you wish to happen?



Should the space stop accepting more entry's?



Should the space swap to disk?



Should the space signal the application in some way?



Should the application do something to manage this situation itself

perhaps by adopting quota's within it's own code?  If not, why not?



What do you expect to happen to throughput in these circumstances?
