   236 Class implementing StartCloseCrazyLoopRConnectionStep

   237 The test does a loop, where every iteration:

   238 (1) Starts the connection

   239 (2) Snoozes for an <interval>

   240 (3) Closes the connection injecting a cancel at that stage of the connection start

   241 (4) Increases the <interval> a bit so that next time round the cancel is injected at a different stage.

   242 

   243 Note that since the test is normally executed by a thread of lower priority than ESock_IP, it relies on

   244 ESock_IP yielding (otherwise it won't test different phases. 

   245 For instance DummyMCPR will artificially yield on TCFServiceProvider::TJoinRequest.

   246 NetMCPR will not normally yield as is. DummyFlowFactory will yield on serving a TFindOrCreateRequest.
