Flavio Crisciani 053a534ab1 Changed ReapTable logic ... - Changed the loop per network. Previous implementation was taking a ReadLock to update the reapTime but now with the residualReapTime also the bulkSync is using the same ReadLock creating possible issues in concurrent read and update of the value. The new logic fetches the list of networks and proceed to the cleanup network by network locking the database and releasing it after each network. This should ensure a fair locking avoiding to keep the database blocked for too much time. Note: The ticker does not guarantee that the reap logic runs precisely every reapTimePeriod, actually documentation says that if the routine is too long will skip ticks. In case of slowdown of the process itself it is possible that the lifetime of the deleted entries increases, it still should not be a huge problem because now the residual reaptime is propagated among all the nodes a slower node will let the deleted entry being repropagate multiple times but the state will still remain consistent.
