```

its possible the memory its trying to remove has already been free'd but not sure.

Start with src/smith/physics/tests/test_dfem_explicit_dynamics.cpp at the ApplicationManager GPU setup and reproduce with tests/test_dfem_explicit_dynamics. Trace the teardown path shown in the backtrace from ApplicationManager destruction through finalizer, terminateDevice, and mfem::Device destruction. Done means the test exits without the Umpire Cannot remove error while retaining the passing simulation test.
