The definition is simple. A mutex is a synchronization primitive
used to allow exclusive access to a shared resource. What you're
talking about isn't the definition, but the interface and semantics.
The design, if you will. This is *precisely* where I'm trying to go
here. I gave a small set of primitives to start with. Now I've
narrowed it even further to a single primitive. Let's decide to
start here and discuss the design and implementation of this
