Subject: re-fix child reaping in wordexp
X-Git-Tag: v1.1.19~13
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=e53296f88952dcc6a9343dea53a4aa911f9a9c87;p=oweals%2Fmusl.git

re-fix child reaping in wordexp

Do not retry waitpid if the child was terminated by a signal. Do not
examine status: since we are not passing any flags, we will not receive
stop or continue notifications.
