To test this issue.

* Open your /etc/hosts and add aliases to 127.0.0.1 with names lh1, lh2, ..., lhn where n is the number of simultaneous sessions to open
* Copy attached opener.html file to the web directory in your serving Tomcat
* Open your java profiler (such as VisualVM) and start profiling your OB instance
* Open with a browser attached launcher.html file, set number of sessions to open and interval in seconds. This will open a new popup for each session.
* Check times and memory consumption.

Executing this test for 20 sessions with 1 second interval, in a standard Openbravo instance removing all widgets in workspace, here you can find times splitted in different methods: https://docs.google.com/spreadsheet/ccc?key=0AmPGxKaZaJn-dGVOMXhGYzRGRlUzNWlmTHFJcGhtUmc&usp=sharing [^]

Also in this test case, analyzing a memory dump got after execution, it can be seen each of the 20 sessions is retaining ~7MB
