While deletion is in progress, the account is locked with the 'deleted' role, which disables all actions with rights control. Todo: * Pretty up the notice on the profile page about the pending delete. Show status? * Possibly more thorough account disabling, such as disallowing all use for login and access. * Improve error recovery; worst case is that an account gets left locked in 'deleted' state but the queue jobs have gotten dropped out. This would leave the username in use and any undeleted notices in place.
