@efriedma-quic I took a second look through all the cleanup routines. `isLeakCheckerRoot(GV)` seems necessary to me even though it's rarely applicable. So I am thinking to keep `cleanupPointerRootUsers` and improve it to cover cases as such as in the issue #64680. This will also prevent any potential failures in valgrind tests.
