      Description

      There have been at least 3 crashes in sharding code caused by use-after-frees or the misuse of references in the 3.1.x cycle: SERVER-19367, SERVER-19839, and SERVER-18815 (the last commit)

      We should proactively search for similar issues to avoid costly debugging later.
