There is currently a project in motion to produce a version of JDOM
which has a reduced memory requirement. However this is not here 
just yet, and will take a little time to refine the balance between
memory usage and CPU occupancy.

We hope to deliver this for the next beta cycle, for more information
on how we intend to reduce memory usage and increase performance you
