    Problem Summary The implementation under test only supports PTHREAD_SCOPE_SYSTEM for
    privileged users.
    Problem Text The test failure for which TSD5TH.00090 was issued against VSTH5.2.3
    still occurs with VSTH5.3.2. A new interpretation is needed to cover
    this failure. In addition, PTHR.os/sched_rt/pthread_attr_getscope
    test 1 produces an Unresolved result for the same reason.
    It uses the routine pthread_attr_init, which tries to set the scope
    to both PTHREAD_SCOPE_PROCESS and PTHREAD_SCOPE_SYSTEM. When
    PTHREAD_SCOPE_SYSTEM fails with EACCESS, it reports that the test
    is Unresolved.

    Although a TSD was previously issued for VSTH5.2.3, it would seem to
    be more appropriate to issue a PIN to cover these failures, because
    the cause of the failures is an additional error condition that is
    not required by the specification, but is allowed under the general
    rules for error conditions.
