Steve Loughran commented on SLIDER-83:
--------------------------------------
The simplest solution here is to have a teardown mode -when set the
{{maybeSaveHistory()}} code will not save its state.
The last state changed before teardown contains all the information needed to
resume placement -which nodes were active at the time the state was saved.
Logging that they were saved prior to teardown is irrelevant.
> RoleHistory to stop logging every released node in teardown
