Research direction

Start by locating the repository's existing image test entry points and the configuration that controls tcmalloc and GLIBC_TUNABLES. Add coverage for tcmalloc.usingPerCPUCaches on MongoDB 8.0 and later, and verify that glibc.pthread.rseq=0 remains necessary; done means the tests detect when either expectation changes.
