That should be sufficient (although the OPENSSL_cleanup() should not be
required).
You could try compiling OpenSSL with OPENSSL_INIT_DEBUG defined, e.g.
perl Configure your-platform-here -DOPENSSL_INIT_DEBUG
This should print out some debugging information to stderr every time
the init functions attempt to do something interesting. In particular
when you call OPENSSL_thread_stop() you should see the following printed
out:
OPENSSL_INIT: ossl_init_thread_stop: ERR_remove_thread_state(NULL)
