The documentation explains:
http://www.boost.org/doc/libs/1_52_0/libs/smart_ptr/enable_shared_from_this.html
<<Requires: enable_shared_from_this<T> must be an accessible base
class of T. *this must be a subobject of an instance t of type T .
There must exist at least one shared_ptr instance p that owns t.>>
