-------------------------------------------

By the way, this is what I see on a passing run:

> ProgrammaticApiTest tests the use of the API for creating and configuring channels. One such test testSharedTransport tests the creation and use of a stack with a shared transport. This test does the following:
> - creates two channels A and B
> - creates a UDP-based shared transport stack
> - assigns the same stack to both channels
> - channel A connects to group cluster-one; channel B connects to group cluster-two
> - channel A multicasts 10 messages to its group; channel B multicasts 5 messages to its group
> - the test then waits for the correct number of multicast messages to arrive
> Problem:the test is failing because the receiver on channel A is receiving 20 messages instead of 10 messages.
> This test fails intermittently, but fairly regularly.
