Madhu and I tried these workflows for a while and found that the memory usage
goes up for opening and closing one workflow. Here is what we tried:
In reporting suite trunk, monitoring using Jconsole
1) open Kepler, 
2) open one Kruger workflow (such as tpc01) from its Kar file
3) close it
4) execute Gabage Collection in Jconsole
5) the min memory after GC goes up for about 20MB

Also from the Allocation Call Tree view in Jprofile, the
org.kepler.gui.kar.OpenArchiveAction.actionPerformed function always hold 20 MB
(mainly for ptolemy.moml.MoMLParser.parse) even after GC. 

We think these two are related, still investigating.
