Comment

  Thread priorities determine which thread to run. Every thread has a priority.
  A thread inherits priority of its parent thread.
  By default thread has normal priority of 5.
  Thread scheduler uses thread priorities to decide when each thread is allowed to run.
  Thread scheduler runs higher priority threads first.
