Terence Yim commented on TWILL-64:
----------------------------------
They are related. I would say TWILL-56 is a prerequisite for this (without
handling the PreemptionMessage, there no way to know when to preserve states.
Handling the message alone, however, doesn't require preserving states. E.g. if
the AM has no state).
> Support work preserving changes for AM restart
