> *Description*
> Occasionally the TM-to-RM registration ask times out, causing the TM to pause
> registration for 10 seconds. Meanwhile the registration may actually have
> succeeded in the RM. Slot requests may then arrive at the TM while RM
> registration is incomplete.
> The current behavior appears to be that the TM honors the slot request.
> Please determine whether this is a feature or a bug. If a feature, maybe a
> slot request should implicitly complete the registration.
> *Example*
> See attached a log showing a certain TM exhibiting the described behavior.
> The RM launched 12 TMs in parallel, evidently causing the RM to sluggishly
> respond to a couple of the TM registration requests. From the logs we see
> that '00012' and '00003' experienced a registration timeout but accepted a
> slot request anyway.
