> {{PersistenceManagerImpl.stop()}} acquires all the permits of {{publisherSemaphore}} to make sure there is no ongoing iteration. But there is no timeout, so if the application is slowly going through all the entries in a huge cache it could block cache stop for a very long time.
> What's more, when a publisher finishes, the stop thread and other threads trying to start a new publisher have the same priority, and if the new publisher acquires a permit stop will have to wait for it to finish.
> We should limit the amount of time we wait for iterations to finish, similar to how {{TransactionTable}} only waits for ongoing transactions to finish for {{transaction.cacheStopTimeout}} millis. Ideally we would move {{cacheStopTimeout}} out of the transaction configuration and use it everywhere we could wait for user threads to finish doing their work before stopping.
