Tor has this functionality built-in, the timeout is configurable (30
seconds by default). Setting too long a timeout is bad if you're a
guard, because the longer you wait to restart the more clients will
rotate away from you while you're down - just restarting without any
timeout at all is rude for anyone currently having an active circuit,
of course.

In short: The default is a sensible compromise, if you run a no-guard
relay you can increase the timeout massively to be "nicer" to people
with long-running connections, if you're a guard you probably shouldn't.

Cheers
Sebastian
