Comment (by intrigeri):

 Replying to [comment:11 mikeperry]:
 > I decided to create a SocksAuthCircuitRenewPeriod torrc option that
 governs how long we extend the lifetime of socksauth-isolated circuits
 each time a new stream arrives on them.

 Would it be an option to allow users to set this with a per-SOCKSPort
 flag, instead of a global torrc option? E.g. Tails has a dedicated
 SOCKSPort for Tor Browser, and I would feel slightly more comfortable
 enabling this longer circuit lifetime for that port only, and leaving the
 default untouched for other applications: my gut feeling is that other
 applications using SOCKS u+p may have different needs, and might be
 negatively impacted by longer circuit lifetime (be it in terms of
 functionality, UX, or anonymity).
