How realistic does the web test mimic reality? Does it completely wait for the test to finish in the normal way a real user would, or does it decide to shutdown all remaining threads generated by the user when a single VU is finished, without giving these threads a chance to complete normally as is done by a real user. I am talking about any asynchronous threads that may still be going at the Server when a user finishes a test and signs out of the web site. Of course many users are doing this concurrently.

There a two-part in your 1st question:
Request concurrency: StresStimulus emulates user load on a protocol level without actually instantiating browsers. However from the server's perspective, emulation is very realistic. Each VU is an independent software object which asynchronously emulates browser behavior, including request concurrency and browser cache. VU maintains several HTTP connections depending on the browser type emulated by this VU, content types of requests and several other factors. VU locks subsequent requests awaiting response from the server. For more on that check this article http://support.stresstimulus.com/display/doc47/Request+concurrency
Test conclusion: StresStimulus behavior at the test conclusion is determined by selected configuration settings as described here http://support.stresstimulus.com/display/doc47/Test-Duration
For example, if you select Secondary test completion conditions as “Wait for Responses” or “Wait for Iterations to Complete” then issue a virtual user will wait for issuing requests or started iterations respectively. But if you select “stop the test” then issued request will be abandoned.
