  27     NOTES
  28         This entry point directly calls task switch routine
  29         in supervisor mode. It neither performs any checks of caller status
  30         nor obeys interrupt enable state. After calling this function, caller's
  31         task will be replaced by another one, and it's caller's responsibility
  32         to do anything to prevent task loss.
  33
  34         This function is safe to call only from within user mode.
  35         This function is considered internal, and not meant to be called
  36         by user's software.
