I'm submitting this to wine-devel because the code is probably messy and I'm not sure if this is the right approach to solving the problem.
This patch adds a new flag and a server reply, allowing GetQueueStatus to ignore internal messages, and MsgWaitForMultipleObjects to process internal messages until a real sent message is found.
