TPL Task Canceled - How Often to Check How to Wait

  I'm not sure if what follows are good ideas, but that's why I'm posting :-)

  I start my MasterProcess (mp) as: var taskProc = Task.Factory.StartNew(() => { MasterProcess(bContinue); }, TaskToken.Token);

  In mp..
  bWait = processNext(dLog, out dNext); // timespan by config file
  While (bWait == false & bContinue == true)
  QueueCheck() // checks log & checks out the next record to process
  if (emailAddress != null & bContinue == true)

  At this point I have a problem because if I have (and I do) an emailAddress then the log for that record is checked out to process, aborting will leave data hanging; Is there a way to remain in the inner loop & continue to process the record which may take 10 seconds (connecting to ConstantContact, getting a response & updating the CRM database & log) - Perhaps a way to set the TaskToken to cannot be cancelled?

  Before I do the next eval on bWait, I first check; if (TaskToken.IsCancellationRequested == true), if so, I then set bContinue = false and all is wright in the world.

  My worst fear is that during the send to CtCt or during the resulting database update the the application will be aborted.

  FYI, although there is a UI for my app it's a server side app that runs to synchronize the CRM with CtCt, so my hope is that since only admin will be starting or stopping it, they'll also be able to deal with any fallout.
