Umm, with that patch, pqsecure_destroy() is never called. The "if
(conn->ssl)" test that's now at the end of the close_SSL function is
never true, because conn->ssl is set to NULL earlier.
I'm afraid the "move_locks.diff" patch you posted earlier is also
broken; close_SSL() is called in error scenarios from
pqsecure_open_client(), while already holding the mutex. So it will
deadlock with itself if the connection cannot be established.
