pmie eventually notices and performs the restart more reliably?  (*cough*)

Yes, and certainly the latter - is this in-progress, or are you expecting
someone else to work on fixing this?

This is a regression that was introduced recently when moving away from the
pmie-based solution (at your insistence), but you seem to have left this BZ
assigned to me ... (as default owner?  hence this followup - please assign to
yourself if you intend to continue working on resolving this, thanks).

Perhaps we should be adding back the more reliable pmie solution, as a safety
net to counter this class of unexpected problem.
