Hi Mathieu,

Scanning all per-CPU slots before the overflow lists
addresses the race where a backup slot can be moved to
a list that has already been scanned.

Using a separate overflow-list phase also decouples list
selection from the wildcard phase.

Thanks for the reviews ! I've picked them up in my own local

tags into the commits he recently picked up.

Thanks,

Mathieu
