Function: LIST queue_info([obj user])
MAP queue_info([obj user])
Returns the number of forked tasks that <user> has at the moment. Since it doesn't say which tasks, security is not a significant issue. If no argument is given, then gives a list of all users with task queues in the server. (Essentially all connected players + all open connections + all users with tasks running in the background.)
If the caller is a wizard a map of debug information about task queues will be returned.
