Hello Ming,

Since there is a significant risk that this patch series will introduce
performance and/or functional regressions, I will wait with reviewing this
patch series further until it has been shown that there is no less risky
alternative to realize the same performance improvement. I think Jens had
already suggested a possible alternative, namely by only starting a queue
if it really has to be started.

Bart.
