 I think sbws was not stalling because of this. We can reopen if needed.

 The following options aren't supported by all Tor versions, we should try
 them in this order, and allow them to fail:
 {{{
 PredictedPortsRelevanceTime 0 seconds
 CircuitIdleTimeout (sbws' circuit timeout)
 }}}
 {{{
 CircuitsAvailableTimeout (sbws' circuit timeout)
 }}}

Comment (by teor):

 Tor stalls when DisablePredicatedCircuits is set at startup, see #17359.
 Maybe tor also stalls after a few days when it is set.

 When #17359 is fixed, sbws should be able to use
 DisablePredicatedCircuits.

 Torflow doesn't stall. I compared the Torflow and sbws tor options. sbws
 sets `__DisablePredictedCircuits 1` and Torflow does not.

 So you could try removing that option from sbws:
