****************************************************************
During a MSD IPL the changed page reclaimator fails, resulting  
in a full directory recovery.  The exception is caused due to  
incorrect information in a page descriptor at the time of the  
MSD.  The incorrect information is seen due to the order of    
updates to the page descriptor.                                

Problem Conclusion

The code which updates page descriptor information is changed to
store the information in the correct order, so that the changed
page reclaimator will no longer take an exception while        
processing.
