Thanks for your patience and perseverance. It looks like it would be too difficult to get SAS PMP working for 2.6.24 merge window open, so I think it is only fair to rescind my assertion of "polling PMP not in 2.6.24 release." Removing the polling remains a design requirement for SAS, but the more I look at old-EH-encrusted libsas, the more work I feel it needs before its ready for PMP. Sorry. Jeff
