ssh-agent is usually started at the beginning of the X session, or from a shell startup script like. It works by creating a unix-socket, and registering the appropriate environment variables so that all subsequent applications can take advantage of its services by connecting to that socket. Clearly, it only makes sense to start it in the parent process of an X session to use the set of decrypted private keys in all subsequent X applications.
