Hakan, Please investigate if this is something that needs to be fixed in Falcon or just the testcase.

The test case was showing long run time on slower machines. I tested it on a idle 450MHz. PPC machine and had a run time of ~ 5 minutes. It's perfectly possible to have a runtime > 15 minutes on busy machines. Fixed by lowering the loop count to 100k. Also created a corresponding -big.test with loop count of 1 million.

Hakan, if the reduction from 500000 to 100000 still causes a timeout on any busy pushbuild system it can be reduced more. Thanks for making the -big test.

Change looks OK to me as well. When you lowered the loop count in the test by a factor of 5, did the running time on your slow machine decrease accordingly (to ~1 min)?

Actually I think I have tested it that it had lower run time, but now compiling on Mac OS X/PPC fails for me with latest sources. I will keep this bug report in "In progress" until I can verify the decreased runtime for sure.

Run time on my 450MHz/PPC with 500k loop count is ~4 minutes and with 100k loop count ~45 seconds.

Test case changes. No changelog entry needed.
