Or maybe it just does not happen in a single-CPU machine, or it does
not happen when the kernel is the kernel from stretch, or something
alike.

Well, I hope you can understand my frustration too: ri-li fails for me
97% of the time (which is almost always), on different machines, and
it seems to fail always as well in the reproducible builds autobuilders.

In such conditions the least I would expect from Markus is to accept
the offer I made (i.e. free access to a machine where this happens always).

Thanks.
