Just to clarify here, Tor's design resists the strategy you describe
here of logging traffic and then later breaking into the Tor relay
to get its key. The long-term identity key for a relay is only used
to sign descriptors.
The actual key exchange for circuit encryption is done with ephemeral
keys, which are discarded when the circuit is done.
