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