"Protected types provide an extremely efficient mechanism; the 
 ability to use the thread of control of one task to execute a 
 protected operation on behalf of another task reduces the 
 overhead of context switching compared with other paradigms. 
 Protected types are thus not only much more efficient than the 
 use of an agent task and associated rendezvous, they are also 
 more efficient than traditional monitors or semaphores in many 
 circumstances."
