Comment 3 for bug 1527710

Eventually the async apt-check is to avoid stalling humans, and there it makes total sense.

We could think to do something like

function checkit {
   *code of the check*
}

if [[ $- == *i* ]];
then
    checkit &
else
    checkit
fi

That would cause the check to be synchronous (as it was in the past), but only if it is a non interactive environment read "nobody directly cares about the sync delay"

Scott, let me know if you - as discussed on IRC in 2016 - could test a deb with that approach that I'd build for you.
