The current signalfd handler cares on CLD_EXITED only. It's pretty insufficient as there is more situations (and codes) when child no more running. Addresses: #686 Signed-off-by: Karel Zak <kzak@redhat.com>

Oh, you have also provided patches. I had read only the issue by email and fixed it by another patch. Sorry. Thanks for you report! |

Running
script --command 'sleep 5', and hitting ctrl+c before the sleep command exits, causes script to hang indefinitely.I've confirmed that this happens with a fresh build from this repository (
script from util-linux 2.32.371-350f) as well as the version from the Arch repositories (script from util-linux 2.32.1). It also happens an Ubuntu Mate 18.04 VM (script from util-linux 2.31.1). It does not happen in an Ubuntu 16.04 VM (script from util-linux 2.27.1).I did a git bisect, and this commit introduced the issue: 2e7a922
