   In a trivial single-tasking test program on my machine, a call to a
Protected function compiled with Gnat 3.15p -O2 takes
  0.304697000 mics while a call to a regular function takes
  0.022779000 microseconds.
Using -O3, it's
0.291347000 mics while a call to a regular function takes
0.001893000 microseconds.
