// = DESCRIPTION
// This program tests thread specific storage of data. The ACE_TSS
// wrapper transparently ensures that the objects of this class
// will be placed in thread-specific storage. All calls on
// ACE_TSS::operator->() are delegated to the appropriate method
// in the Errno class. Note that each thread of control has its
// own unique TSS object.
