        * rw_allocator.h (n_throws_): New member array to keep track
        of the number of exceptions thrown from each member function.
        * allocator.cpp (SharedAlloc ctor): Zero-initialized all arrays.
        (funcall): Incremented the member function call counter regarless
        of whether the call results in an exception or not to parallel
        the same algorithm used in operator_new(). Incremented the
        exception counter, n_throws_, for each thrown exception.
