Description Bernd Hufmann CLA 2010-11-25 15:59:47 EST 
Build Identifier: 

When selecting an experiment, the previous loaded experiment is not cleaned-up properly, which causes a memory leak. The size of the leak depends on the size of the previous loaded experiment (number events).

Reproducible: Always

Fix for memory leak

This patch fixes the memory leak. Before processing the new experiment, the old experiment will be clean-up and all relevant references in the LTTngTreeNode structure  (experiment and traces) will be removed. By doing that also the garbage collector can clean up the unused objects (including the checkpoints!).
