 Replied there.

 Agreed.

 Replying to [comment:7 teor]:
 > (It's pretty safe, because it only extends the systemd timeout. But we
 should check it doesn't extend the timeout too much.)

 As I explained on the PR, it doesn't matter too much if the number sent is
 too high, since systemd will continue immediately as long as tor actually
 exits before the timeout (it's a maximum limit, not a minimum or exact).
 If tor doesn't exit expeditiously, then that's a bug in tor. IMO it's
 worth trying to work around the (still hypothetical AFAIK) bug by waiting
 a little longer, rather than crashing and almost certainly corrupting
 cache files. Also, I figure nobody will care excessively if they set
 ShutdownWaitLength to 2 minutes and tor actually takes 2 minutes 15
 seconds to quit, as long as we don't accidentally make it 20 minutes (but
 again, that would require another separate bug in tor).
