Allow `SellRewards` just before `FetchPoolPrice` #551

Closed ruuda closed 2 years ago

ruuda commented 2 years ago

As pointed out by Neodyme, a malicious cranker could spam FetchPoolPrice transactions, and although eventually the SellRewards should win if there is some probability for either transaction to win the race, this could delay selling for the rewards for some time. To mitigate that, give SellRewards a head start of one slot, so if there are two crankers that are spamming FetchPoolPrice and SellRewards, the SellRewards would win.
