+The CacheStress.cs test is a standalone test that should be compiled and run
+as a console application.
+In normal mode the test prints every 10 seconds the number of transactions it
+committed.
+In case of an exception the test prints the exception and continues. In case
+of a deadlock the transaction count will remain constant.
+Note that the test does not run in .Net on Windows since the System.Web.Caching
+of .Net cannot be used from a console application. Mono's implementation does
+not currently have this dependency. When (and if) it does this test should
+be made into a Web application.
