Description Steffen Kriese CLA 2011-06-28 02:30:56 EDT 
While a Riena-Application is running its CPU-load is constantly getting higher. 

Steps to reproduce:
- Start the Riena-ExampleClient in debug mode
- Go to the debug persepective
- Have a look at the Debug-View: There should be about 8 worker-threads runnning.
- Open the Windows Task-Manager and check the CPU load of the runnning application. It should be 0 %
- Wait for at least 15 - 30 minutes and keep the application runnning
- The number of working threads is growing without any interaction with the application!
- Also the CPU-load in the Windows Task-Manager is getting higher and higher. On my machine to about 11 % after 15 minutes.

This could be related to Bug 348681, because if we start UIProcesses the CPU-load seems to increase faster.

Patch for the Riena Exampleclient

This is the patch from Bug #348681

It seems that starting UIProcesses increases the CPU-load. To reproduce:

- Apply the patch
- Start the ExampleClient in debug mode
- Go to Playground => UIProcess
- Switch between the submodules Demo1 and uiProcess_2 and check the number of worker threads in the debug view

Fixed in HEAD.

The list of JobChangeListeners for each job grew over the time and slowed down the application.
