      Description

      In a GaudiPython script, memory usage increases linearly, upto 5+ GB for a few thousand events. No problem in ROOT 5.

      I've run the script through valgrind with memcheck and massif; 100 events for memcheck and both 1 and 100 events for massif and I attach the logs here. Marco Clemencic should be able to allow you to run the script, if needed.
