// apparently attributed large stacks and pages of memory are not regained by the system maybe because it thinks
// that RS will use them again.
//
// * the deep check should be implemented differently, in an incremental way. For instance in notifyChanges() of each
// service (e.g. channels here) should update the index when a new message is received. The question to how old messages
// are processed is open. I believe that they shouldn't. New users will progressively process them.
//
// * integrity check (re-hashing of message data) is not needed. Message signature already ensures that all messages received are
// unalterated. The only problem (possibly very rare) is that a message is locally corrupted and not deleted (because of no check).
// It will therefore never be replaced by the correct one from friends. The cost of re-hashing the whole db data regularly
// doesn't counterbalance such a low risk.
