We need them both, yes.  The second one was introduced for a reason,
so removing it would give us back the problems it solved.

setlinebuf is not portable enough, and line buffering isn't supported
on MS-Windows anyway.  Maybe we could make some archlinux specific
change, although that's ugly.

And I'm worried that we don't actually understand the nature of the
problem well enough: our code doesn't close both FILE streams, it
closes at most only one.  So this sounds to me like a false positive
of the sanitizer, not a real problem with our code...
