Issues that this hotfix rollup fixesIssue 1

The ResourceManager has a race condition in AddResourceSet. When multiple threads are adding resourcesets, ObjectDisposedExceptions occur.

For example:

ResourceManager uses one ResourceSet for potentially multiple cultures, such as fr-FR and fr. If you add one culture (like fr-FR) on one thread and then add fr on another thread, the first thread may try to add its ResourceSet for fr. In this situation, the first thread will close the already-added resource for fr-FR, and that causes ObjectDisposedExceptions on other threads.

Issue 2

When you try to run a command on the server, it time outs on the client-side, but finishes on the server. Then, the client sends an attention packet to the server, and sets itself into a timed-out state. However, the client doesn't reset the state as soon as it recovers from the time-out if the server processed the statement that the client timed out on.

This fix resets the state for the client when it can recover from a time-out.
