That is right.
With 2.1 we will change that so that only the gpg-agent performs any
private key operations and the gpg2 processes care only about session
keys. The latter is not really problematic given that the plaintext is
usually also in RAM and thus a lower hanging fruit. (gpgsm already
works like this).
