- * This function is a hack, intended to minimize impact of not fully implemented power management support
- * on OSX guests. We do nothing smarter than make access to certain register (ISR status for LVT[6])
- * rather long operation from the guest's perspective. 
- * To be removed once real reasons why power saving states not reached by OSX will be figured out.
- * Hack seems to be safe, as guests rarely access this particular register.
