If I remember right, a circuit will accept new streams (usually meaning
new connections to servers) for a maximum of 10 minutes.

However, once a  connection has been established, the circuit it's using
will remain open until:

1.) The application closes the connection (if it reconnects, it'll use a
new circuit);

2.) The circuit "dies," like from a node or a link going down.
