Returns false, as I mentioned twice above. Also returns a PHP warning.
I got some more info now. The error message they get is
"session_destroy(): Session object destruction failed".
On my test page, with simply a session_destroy() before any
session_start(), the error (warning) message is "Trying to destroy
uninitialized session". This happens both on PHP 4.4.4 and 5.2.1.
So, these are different...
