I did not read all of it, but the conclusion is that
context switches are bad for performance.
If a protected object can REPLACE a task, it
will show in measurements. (and they did measure)
However, it is tested with gnat 3.10,
so things might be different now.
And I now learned that render-vouz is spelled rendezvous
