Changing LockedPageManager to use a managed instance
This ensures the allocator is ready no matter when it's needed (as
some STL implementations allocate in constructors -- i.e., MSVC's STL
in debug builds).
Using boost::call_once to guarantee thread-safe static initialization.
Adding some comments describing why the change was made.
Addressing deinitialization of the LockedPageManager object
by initializing it in a local static initializer and adding
an assert in the base's destructor.
