We encrypt (using 2-way encryption, not hashing, for obvious reasons) 
passwords
in session data, to avoid having cleartext passwords in the session 
store. It's
not foolproof at all, but it means that someone who gains access to your
server's session store doesn't *automatically* have all the passwords in it.
That requires actually doing encryption, and mcrypt, being written in C, is a
much faster way of doing it than the PHP-native code we fall back on if mcrypt
isn't available.
