OT launchd sleep and wake

[Kristofer Henriksson]

Off the top of my head, I can't speak as to detecting sleep/wake on a Mac.

For clearing SSH keys, I'm surprised that stopping ssh-agent fails.
However, there is also the command ssh-add -D which is meant to remove
all keys from the agent. This should be what you are looking for.
