> 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.
> See attached a log showing a certain TM exhibiting the described behavior.
