            Description

            In some rare cases, it was observed that the CT17: Connection Manager test fails when the RPI is set to 10 ms.

            The cause was a race condition, when, in parallel, a class 0/1 connection timed out and a new TCP stream was opened. Then the stack closed the new stream immediately, where it should only have closed the causal TCP stream over which the class 0/1 connection was opened.

            The timing of RPI=10ms tuned out to be just in in the "sweet spot" to reliably trigger the issue once in a few test runs.
