Using valgrind on one of my tests I get the follow results

Here's the code used during connection shutdown:
if (connection->sslSocket != NULL) {
PR_Shutdown(connection->sslSocket, PR_SHUTDOWN_BOTH);
PR_Close(connection->sslSocket);
}
SSL_ClearSessionCache();
NSS_Shutdown();
PR_Cleanup();
Most of the leaks look like allocations made by NSS_Init are there
other calls I need to make to fix these leaks?
