RFR: Revert "Mutator may fail to evacuate"

Wed Mar 9 00:07:54 UTC 2022

This reverts commit 2132a6d151e4c46b71a220100fa478a8be676f13.

We found that the solution implemented in this commit is insufficient to address the problem.  We need to redesign the OOM protocol for evacuation allocation failures.  This is being explored by other engineers.
