Patch Set 2: Do not submit; No score

The tests test80000 and test99999 fails occasionally here.
It's just a little worse than the limit set.

The off-factor for test80000 varies up to 18 here.

One thing to keep in mind when doing performance tests is the limited resolution of System.currentTimeMillis, but
also that it measures elapsed time and not CPU time.

Look here for hints on measuring CPU time.

I tried this, but it seems the tests are too short. Repeating them ten times seemed to work...
