/**
 * A fix for a bug in the Hotspot VM which renders the ForceTimeHighResolution
 * switch useless. And there for makes it impossible to get Thread sleep times
 * small as 1ms. Starting such Deamon Thread as in the bottom with an sleeptime
 * which is not a multiply of 10 sets the OS somehow into the high performance
 * timeing mode.
