Ada ones imply protected objects. The problem is that it would drag  
the tasking runtime in all occasions, even if you intend to write a  
client or server without explicit
needs for tasking. Here, we can have no-op mutexes for no tasking, PO- 
based mutexes for tasking, and can adapt them for other runtime that  
are purely POSIX, or other API

It is the same rationale for conditional variables and threads
