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
