6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Matthieu Baerts (NGI0) <matttbe@xxxxxxxxxx>
commit 41b02ea4c0adfcc6761fbfed42c3ce6b6412d881 upstream.
If errexit is enabled ('set -e'), loopy_wait -- or busywait and others
using it -- will stop after the first failure.
Note that if the returned status of loopy_wait is checked, and even if
errexit is enabled, Bash will not stop at the first error.
