SSL is not guarded via mutex in httpserver

[adarovsky]

Hello.

I use XMLRPC server built on top of Pylons. This server uses OpenSSL with certificates for security.

I think I've found a bug. If I create a minimal app with one 'ping()' method and start a stress test with it, I get the following error:

error:140943FC:SSL routines:SSL3_READ_BYTES:sslv3 alert bad record mac

After that server responds on every request in this way until it's restarted. On x86-64 systems this causes server to hang completely

If I make the following changes:

httpserver.py:317:

from OpenSSL import SSL, tsafe

httpserver.py:363:

self.socket = tsafe.Connection(ssl_context, self.socket)

and add 'settimeout' to list of guarded functions in OpenSSL/tsafe.py error seems to go out
