Can not cancel build

[DrRac27]

If I run e.g. a command like guzuta build --arch $PKG_ARCH --chroot-dir ./chroot-$PKG_ARCH --repo-name $PKG_REPO --repo-dir ./repo/$PKG_REPO/$PKG_ARCH --srcdest ./sources --logdest ./logs PKGBUILDS/$PKG_REPO/$PKG_NAME I can not cancel the build using Ctrl+C. If I do so guzuta stops but makechrootpkg still runs in background and prints to stdout. Pressing Ctrl+C again has no effect and the only way I found to stop it is sudo killall makechrootpkg. Then it prints ==> ERROR: Aborting... and stops the build. What I would expect guzuta to do is forwarding the signal that stopped guzuta to all child processes.
