gh-140814: Fix freeze_support() setting start method as side effect (GH-144608)
...
freeze_support() called get_start_method() without allow_none=True,
which locked in the default start method context. This caused a
subsequent set_start_method() call to raise "context has already been
set". Use allow_none=True and accept None as a matching value, since
spawn.freeze_support() independently detects spawned child processes.
Test that freeze_support() does not lock in the default start method,
which would prevent a subsequent set_start_method() call.

gh-122575: gh-142349: fix sys.flags tuple size (it unintentionally increased) (GH-145988)
...
the lazy imports PEP initial implementation (3.15 alpha) inadvertently incremented the length of the sys.flags tuple. In a way that did not do anything useful or related to the lazy imports setting (it exposed sys.flags.gil in the tuple). This fixes that to hard code the length to the 3.13 & 3.14 released length of 18 and have our tests and code comments make it clear that we've since stopped making new sys.flags attributes available via sequence index.
