Moshe is forgetting:

ContinueMePleaseError = "please continue" # or a class if you prefer that
while binAliveMarker:
  try:
    if binWannaStartAgainLater:
      time.sleep(1)
      raise ContinueMePleaseError
    work code ...
  except ContinueMePleaseError:
    continue
  except:
    pass

which is the usual way of working around it (other than reworking your code,
that is.)
