[boost] noncopyable

I had a thought today that the default constructor for noncopyable ought to
be protected, to emphasize that it was only useful as a base class.

Then I thought that maybe noncopyable& would also make sense as a template
selector parameter, like a trait value.

Then I thought that template selectors probably ought to be able to be
passed by value, so noncopyable isn't a good candidate for use as a template
selector.

So I'm leaning towards a protected default constructor.

Opinions?
