When uplink connections fail through timeout, some packet flow hangs seem to occur; workers get internally delayed packets. Is a lock being held or something?
Probably the worker was stuck on uplink_close() of a second uplink (trying to connect to a server which rejected login), which obtains uplink_client_mutex. make_uplink() holds uplink_client_mutex for the duration of the connection attempt. This deadlock should be fixed.
