Did you found time to try out my POD mutex?
I would be very interested if you could comment on it.

This mutex can indeed be safely used with any storage duration.
The fact that it has to be initialized when used as a member
of an object is not anything more strange than the requirement to
initialize an integer before first use.

Not sure what this exactly means, can you exemplify?

Which kind of named are you talking about here?
I do not believe opsys-named is the correct way to go.

If you think the simplest interface is doing away with the mutices
altogether I am with you.

scoped_lock lk(&foo); should be enough. Implementing this efficiently
however is another story.
