On further thought, since context deletion tokens are obsoleted, and
have been for a long time, we might as well say nothing about
GSS_S_COMPLETE implying that the peer is done using its side of the
security context.  The GSS_S_FAILURE case, however, still kinda leads to
the caller being done.

OLD PROPOSED TEXT
|      Though future GSS-API extensions may add new uses of asynchronous
|      security context tokens and ways to process them, applications
|      using the GSS-API version 2, update 1, should generally call
|      GSS_Delete_sec_context() after calling GSS_Process_context_token(),
|      when the latter returns GSS_S_COMPLETE or GSS_S_FAILURE.

NEW:
|      Applications should generally call GSS_Delete_sec_context() when
|      GSS_Process_context_token() returns GSS_S_FAILURE.
