pythongh-88496 replaced text.update with text.update_idletasks in two files to fix test failures on macOS. While theoretically correct, the result was Shell freezing when receiving continuous short strings to print. The guess is that there was no idle time in which to do the screen update. Reverting the change in one of the files, outwin, fixes the issue. The test will be patched as needed on macOS.

When running test-outwin on macOS, alias 'update' to 'update_idletasks on the text used for testing.
