Um. So there is a block in Arguments::check_vm_args_consistency():

  if (FLAG_IS_DEFAULT(LoopStripMiningIterShortLoop)) {
    // blind guess
    LoopStripMiningIterShortLoop = LoopStripMiningIter / 10;

Is that block misplaced? Should be removed, if we init this per-GC? Or, it should be moved somewhere
after GC argument initializations?
