Description

This test seems to flake pretty quickly for me under system stress with aed0b871479,

[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from HierarchicalAllocatorTest
[ RUN      ] HierarchicalAllocatorTest.MaintenanceInverseOffers

When saturating my system with stress-ng this test only succeeds ~30% of the time.
