Here's a lightweight starvation free (ticket based, no preference)
reader-writer lock.

It only works with vc++ right now, you'll have to change a
_InterlockedCompareExchange() and Sleep() for other platforms but that
should be easy.

Otherwise it follows the boost model already, but uses
scoped_read_lock and scoped_write_lock instead of just scoped_lock.
