Fixes #14985.
When IPython is started via
start_ipython()inside an existing Python interpreter on Windows, the temporary history SQLite database may remain open during shutdown. Since Windows does not allow deletion of open files, cleanup of temporary history files can fail with:PermissionError: [WinError 32] The process cannot access the file because it is being used by another processThis change explicitly stops the history-saving thread (if present) and closes the history database during
_atexit_once()before temporary files are removed.
