Multiple ssh sessions with low overhead

dbtfeed tipped me to this, answering someone else's question on IRC.

If you need to run multiple simultaneous or successive ssh connections to the same host, OpenSSH 4 and later have a mechanism to do this with minimal overhead. ControlMaster lets you do the key exchange once, and routes successive connections through that session.
