-    Maximum amount of resources above the target capacity ignored for preemption.
-    This defines a deadzone around the target capacity that helps prevent thrashing and
-    oscillations around the computed target balance. High values would slow the time to capacity
-    and (absent natural.completions) it might prevent convergence to guaranteed capacity.

-    Given a computed preemption target, account for containers naturally expiring and preempt
