I'd do the traces if I were you. Maybe it's something to do with "Thread 
Sorts By Arrival" or similar Alpine threading quirks. There was also 
traffic a couple months ago about threading scaling non-linearly in Alpine 
depending on that setting. I assume you're running a recent snapshot, but 
I don't recall whether that issue was resolved.
