    gh-90876: Restore the ability to import multiprocessing when `sys.executable` is `None` (#106464)
    
    Prevent `multiprocessing.spawn` from failing to *import* in environments
    where `sys.executable` is `None`.  This regressed in 3.11 with the addition
    of support for path-like objects in multiprocessing.
    
    Adds a test decorator to have tests only run when part of test_multiprocessing_spawn to `_test_multiprocessing.py` so we can start to avoid re-running the same not-global-state specific test in all 3 modes when there is no need.

    gh-104584: Clean up and fix uops tests and fix crash (#106492)
    
    The uops test wasn't testing anything by default,
    and was failing when run with -Xuops.
    
    Made the two executor-related context managers global,
    so TestUops can use them (notably `with temporary_optimizer(opt)`).
    
    Made clear_executor() a little more thorough.
    
    Fixed a crash upon finalizing a uop optimizer,
    by adding a `tp_dealloc` handler.
