commit 2e920a212fbe2de705811d547c169c1ae1611a02
Author: Evgeniy Naydanov <evg...@sy...>
Date:   Wed Nov 22 18:10:27 2023 +0300

    break from long loops on shutdown request
    
    In loops that typically take longer time to complete, check if there is
    a pending shutdown request. If so, terminate the loop.
    
    This allows to respond to a signal requesting a shutdown during some
    loops which do not return control to main OpenOCD loop.
