Comment:

 Ok this has been introduced with commit:
 `d5a151a06788c28ac1c50398c6e571d484774f47` (tor-0.3.1.1-alpha).

 Which adds this 60 sec idle timeout for the first 100 circuits to
 `origin_circuit_new()`

 In a nutshell, every tor client >= 031 are doing that behavior and that is
 an intense pressure on the network. At least no data is going on those.
