Also it strikes me that maxSavePostSize should really be backed up by a 
use of a SoftReference in SavedRequest.

This would allow one to allow relatively large POST bodies to be saved 
unless/until this threatened to consume the JVM's overall memory 
resources, at which point the POST bodies could be dropped.

As it stands now one has to choose between vicious treatment of large 
POST bodies (i.e. dropping all the user's data) and opening oneself wide 
open to quick and easy (and possibly accidental) DOS attacks.
