[svn-r13953] Purpose: Fix test

Description:
    Compilers don't destroy temporary objects at the same time, some do
    immediately after use, some delay until the end of the scope.  The
    delay makes it difficult to test the reference count functionality.

Solution:
    Enclosed the operations on objects and check reference count after
    getting out of the enclosed block.  This only works for the test!
    I'm assuming that checking reference count is just for the library
    to test that functionality; the user will not need to do that. :-/

Platforms tested:
    SunOS 5.10 (linew)
    Linux 2.6 (kagiso)
