class to manage an instance pointer to ACE_TSS_Cleanup. Note: that the double checked locking pattern doesn't allow safe deletion. Callers who wish to access the singleton ACE_TSS_Cleanup must do so by instantiating a TSS_Cleanup_Instance, calling the valid method to be sure the ACE_TSS_Cleanup is available, then using the TSS_Cleanup_Instance as a pointer to the instance. Construction argument to the TSS_Cleanup_Instance determines how it is to be used: CREATE means allow this call to create an ACE_TSS_Cleanup if necessary. USE means use the existing ACE_TSS_Cleanup, but do not create a new one. DESTROY means provide exclusive access to the ACE_TSS_Cleanup, then delete it when the TSS_Cleanup_Instance goes out of scope.
