score: _Thread_Dispatch_disable_critical()
Thread dispatching is disabled in case interrupts are disabled. To get
an accurate thread dispatch disabled time it is important to use the
interrupt disabled instant in case a transition from an interrupt
disabled section to a thread dispatch level section happens.
