Bug description:
Every time pam_ecryptfs is called by the PAM stack, it will use the entered password, decrypt the wrapped-passphrase, key-strengthen that, load the results into the keyring, and then mount the user's private directory.

If the user's home (or private) directory is already mounted, this is a tremendous waste of time/effort.

We should short-circuit this process if possible.

Note that the counter aspect of this is going to be tricky...
