For the Neutron "ssh timeout" issue [1], we think we know why it's
spiked recently. This tempest change [2] may have made the situation
worse. We'd like to propose reverting that change with the review here
[3], at which point we can resubmit it and continue debugging this.
But this should help relieve the pressure caused by the recent surge
in this bug.

Does this sound like a workable plan to get things moving again?

Thanks,
