          SCLP Info Area Lock:
          This lock must be held shared if SYSSCPBK, the pointer to
          the SCP Info Area is used to access the SCP Info across a
          loss of control.  If a 'snapshot' access is done using
          SCPSCPBK, without loss of control, the lock is unnecessary
          since the release of the SCP Info area is done via an
          MPDFR call to HCPSASRL.  This lock is meant to prevent
          the SCP Area being release because of an SCLP Configuration
          Management Data event, event qualifier 4, which may change
          the installed CPU facilities.

                                            The run-time value of the
                                            system's POSIX {NGROUPS_MAX}
                                            value is contained in SYSNGMAX.
                                            This value is initialized to CP's
                                            native value, but an ESM can
                                            provide a larger number. A
                                            POSIX-capable ESM is required to
                                            notify CP of its presence and its
                                            {NGROUPS_MAX} value. The SYSPXESM
                                            byte is manipulated with TEST AND
                                            SET, and only the first task that
                                            sets it to X'FF' will modify
                                            SYSNGMAX. Thus the ESM may supply
                                            its {NGROUPS_MAX} value only
                                            once.
