Major Description
The yoko default concurrency model is "thread_per_client", which uses a single thread for all requests coming from a client application. This can lead to deadlock situations with applications that have been ported from other ORBs because additional requests from a client get queued up behind the currently active request. This situation is EXTREMELY difficult to diagnose, since the application will just hang without any diagnostics on the situation. Neither the Sun ORB or the IBM ORB display this behavior, so the safer default concurrency model would be to use a thread pool to dispatch requests.
