graceful shutdown of TOR

[Michael Holstein <michael.holstein@xxxxxxxxxxx>]

is there a graceful way to shutdown TOR so that you don't kill any of 
the existing connections?

Does editing the config to stop advertising the OR/DIR ports and sending 
a HUP do the trick?

Or is this something I should even really worry about, since the client 
will quickly realize the path failed and choose another node?

Thanks,
