I didn't go that route because I don't like disabling tests without
understanding why they fail and it took me a while to understand the
zombie root cause. In addition to that, without the testsuite passing I
didn't feel confident that I would be proposing a good enough package
because virtually the only part of public-inbox that I use is lei
itself. What if there was a regression in other parts of it and I didn't
notice because I use so little?

But I wouldn't mind disabling the part that checks that lei-daemon is
truly gone, or even the whole testsuite if that is too complicated.

On the other hand, the preferred solution would be the workaround
pointed out by Maxim, where tini is used to run the testsuite and reap
its sub-processes. I can probably take a stab at it over the weekend if
no one beats me to it.

I don't, but it looks interesting! I'll try it out, thanks!
