* 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.
