Description: Eliminates the use of the resource tracker on shared memory segments but preserves its use on semaphores, etc. where it is appropriately applied. Adds a test that fails with the current code (an independent Python process started via subprocess accesses shared memory created by a different Python process, then exits normally, expecting the original creator process to continue to be able to access that shared memory) but passes with this patch to defend against future regressions. https://bugs.python.org/issue38119 Issue: gh-82300
