4 * @file Object_Manager_Flipping_Test.cpp
7 * Tests the basic function of the ACE_Service_Config in scenarios
8 * where the ACE_Object_Manager is being
9 * flipped. i.e. ACE::init/ACE::fini() are called in sequence
10 * (which can occur with loading DLLs). More specifically we test
11 * that the OM correctly controlls the lifecycle of the default SC
12 * instance, which is pointed to by a TSS pointer.
