Let's not forget that CHIL provides one very unique feature - forked
process keeps the authentication state of its parent and can access HSM
keys if its parent was authenticated. PKCS#11 specification prohibits such
behavior (PKCS#11 v2.20 chapter 6.6.1) and because of that PKCS#11 based
engine couldn't fully replace CHIL engine.
