You sir are a miracle worker, my hat is off!

The responsiveness of everything is better than it's ever been, my
users will think this is the best feature the upgrade.

For example earlier today I managed to launch 10 VMs in parallel,
eventually, I'd guess on the order of 5-10min.  One of my usual
acceptance tests is being able to launch 100 VMs in that time.  Just
now Iaunched 100 in <2min from request until they'd all been
provisioned and were booting.  Now there's too many moving pieces and
too few experimental samples to make any publishable claims, but your
patch is the only thing that changed.

Thanks,
