Summary: socketmodule SSL free calls in wrong order
Initial Comment:
I was examining socketmodule.c and notice the following ordering of
allocation and deallocation regarding SSL.
static SSLObject *
newSSLObject(PySocketSockObject *Sock, char *key_file, char *cert_file)
{
...
self->ctx = SSL_CTX_new(SSLv23_method()); /* Set up context */
...
self->ssl = SSL_new(self->ctx); /* New ssl struct */
...
}
static void SSL_dealloc(SSLObject *self)
{
...
SSL_CTX_free(self->ctx);
SSL_free(self->ssl);
...
}
Perhaps it works for now, but I think that the order of free() calls in
SSL_dealloc should be reversed.

Ah, or https://sf.net :)
Maybe add this as a test case to test_socket but don't bomb
out if that host isn't responding or reachable?

Testing SSL support is easy in interactive mode, e.g.
urllib.urlopen("https://www.openair.com/index.pl")

I believe it is easy to fix (see attached patch), but I
don't have a way of testing it. There appears to be no
regression test for SSL support, nor is there documentation,
so I have no idea how to /use/ the SSL support in socket module.
Assigning back to Jeremy to double check the patch.

Barry, This is a memory leak/free problem, right? So you
get it. Seriously, sounds like this would be easy to fix.
