Tor fails to reconnect after computer resumes from sleep

A user reports that tor 0.2.9.x does not work after resumes, similar (or the same as) bug legacy/trac#19969 (moved), marked already fixed.

https://bugs.debian.org/853146:

Tor (or tor with little t) doesn't reconnect automatically to Tor network after I resume my computer from sleep. So instead I have to run "sudo systemctl restart tor" to get it working again. Though, I think it reconnects automatically after several minutes of computer being on but I would like it to reconnect immediately after the computer has resumed from sleep.

I'm not sure if tor uses systemd but so if it uses maybe there is some 'resume sleep' hook in systemd that could be used for tor to reconnect. Please let me know if you think such change would cause some other problems.
