  Log:
  SVN rev 212958 on 2010-09-21 08:02:02Z by mav
  
  Until hardclock() and respectively tc_windup() called first time, system
  is running on "dummy" time counter. But to function properly in one-shot
  mode, event timer management code requires working time counter. Slow
  moving "dummy" time counter delays first hardclock() call by few seconds
  on my systems, even though timer interrupts were correctly kicking kernel.
  That causes few seconds delay during boot with one-shot mode enabled.
  
  To break this loop, explicitly call tc_windup() first time during
  initialization process to let it switch to some real time counter.
