commit 30bd9c2dbd381f4cee922f25d10b6f7ef332f4e9
Author: Thibaut VARÈNE <hacks at slashdirt.org>
AuthorDate: Thu Oct 20 15:48:04 2022 +0200

    phase1: remove dead code due to shared_wd=1
    
    shared_wd is always set, the conditional on these bits were thus always
    the same resulting in dead code.
    
    Remove 'expire' config option which is no longer needed.
