Make after-startup shmem failure test reliable The test expects a 128 kB request to exceed the shared memory available after startup. Huge pages can round up the main shared memory segment enough for that request to succeed, defeating the test.
Disable huge pages for the allocation-failure phase so that it exercises the intended error path independently of shared memory segment rounding.
