Um. Maybe I'm missing something here, but this doesn't make any sense to
me at all. The whole point of scoped_lock is that the lifetime of the
mutex and scoped_lock lifetimes are *different*. Furthermore, you're not
actually locking anything with your Lock class... you'd simply get a
different mutex for each instance of Lock you create.

In short: You'd need two wrapper classes, one for scoped_lock and one
for mutex. Which means you might as well just use boost::mutex and
boost::scoped_lock.
