* Bug 239:
*
* SUMMARY: Crash in a slack-multi-threading mode when returning from the method experienced exception
*
* Note:
*
* Run this in a slack mode (use AcpiExec -s <this_demo>)
* by the Threads debug operation on more than one thread
* (use <Threads 2 1 main> command). In this case the example
* causes crash of AcpiExec for any exception occured during
* execution of methods (m000, m001).
