assorted algorithmic fixes from Paolo Valente (one of my qfq coauthors):
- use 1ULL to avoid shift truncations
- recompute the sum of weight dynamically to provide better fairness
- fix an erroneous constant in the computation of the slot
- preserve timestamp correctness when the old timestamp is stale.
