create update record for accounts on directory server itself during profile changes, re-queue failed directory sync packets, fix account_id index in queue creation, be more selective about updating hubloc_connected (only when we're talking to the associated site). But we still need a way to flag dead accounts and these mechanisms won't cut it, because it isn't a requirement that channels communicate with anybody, except for contacting the directory when the account is created. I think we need to make every channel ping the directory once a month. Then we can find those that have not done so (after syncing with other directories). We can't have the directory just flag dead accounts as this would create a way for an anti-social attacker to become a directory server and mark all the accounts dead.
