…ythongh-155365) In the free-threaded build, new_threadstate() reserves a QSBR thread-state slot before it can still fail for other reasons, but the failure paths only called free_threadstate(), which does not know about the reservation. Restructure code so failure path doesn't leak. (cherry picked from commit 44e92d4a5922dd8fa61f75834784c2772fdd34ab) Co-authored-by: Neil Schemenauer <nas-github@arctrix.com>
