notarytool submit --wait has no timeout. On 2026-10-02 it hung for
over 5 hours in a main build. Since #16044 a new push no longer
cancels a running main build, so nothing stopped it and six waiting
main runs were replaced without starting.
Over the last 30 days the step succeeded 206 times, with a median of
4.3 minutes and a maximum of 14.8.
