Description

When unspecified exception occurs inside handler, TTwisted server disconnects the client.

Many other languages and non TTwisted/Tornado servers sends TApplicationException in such cases.
There is even a test case that tries to assert this behavior for TTwisted but the test is broken in a way it fails to detect the failure.
