Going a bit OT here, but I'm pretty sure there are a fair few Mac users here: has anyone noticed the ssh-agent/OSX Keychain integration behaving differently in Lion compared to previous versions?

In the past, I'm sure that waking the laptop from sleep, or unlocking the screensaver also unlocked the login keychain, and with it updated ssh-agent with my priv key, but recently I've been having to manually unlock it, which is getting to be quite a pain.

(ssh-agent remains running the whole time, ssh-add -l shows the identity when the login chain is unlocked, but is empty otherwise)
