/*** NRH's Alpha2 timer expires. We enter Hybrid mode.***/
	//Test that we do not get response before alpha2 has expired
	// The way the test works is to check first that the response is not received too early, 
	// that is, not within the period (t - delta).
	// Then it checks the response IS received within the period t + delta (so 2 * delta
	// after the previous check).
	// If both these tests are satisfied, then the test passes.
	// There is a problem though. Because the protocol module involves lots of
	// state transitions for any request, and the priority of its active object is set low to avoid 
	// hogging system resources, it occasionally happens that a delay creeps in before the
	// request gets as far as the NRH. 700ms has been observed.
	// This means that the WaitForResponse() here, which takes its startpoint from 
	// the issuing of the request, sometimes times out even though the NRH, left for a bit longer,
	// would time out correctly and return the expected response.
	// We could just change delta to a large enough value (say, 1 sec) to cover this, but
	// this might end up concealing a real problem if it happened that a consistent delay was 
	// introduced for some other reason.
	// So the solution is to behave as described above, but in the case where the response is not 
	// received within (t + delta), we wait for a further second. If the response is
	// still not received, then the test fails. If it is received in this extra period,
	// the test result is set to EInconclusive, to indicate there's something we're
	// not happy with, without its being a complete failure. If the test consistently 
	// finishes with an EInconclusive result, then that is an indication that it ought
