* test_FlowRuntime.cs:
  High_prio_exception_message_terminates_runtime fails as the default
  scheduling was changed with commit
  9133bc4ffdeaf5f3582cb5b185a87f81a37c378b "Switched to async depth
  first default scheduling" which violates the assumption initially
  made for this test; to get this test running successfully the
  scheduling strategy is specified explicitly to be
  breadth-first-processing which ensures that the exception coming
  last in the continue actions is processed before the flow runtime
  continues to process the first action in the continueWith list

* test_causality_handling.cs:
  Causality_exception_messages_bypasses_other_pending_messages fails
  as the default scheduling was changed with commit
  9133bc4ffdeaf5f3582cb5b185a87f81a37c378b "Switched to async depth

eliminated mon compiler warning for generic type parameter by giving a
second independant type parameter in an inner generic class another
name than those from the outer class
