Hi!
Honestly I'm not sure what we should do about this test. Obviously this
is a step into right direction but it still keeps the SUCCEED_OR_DIE()
macro that produces many warnings.

I'm also not happy about the fact that we compile different test based
on ifdefs and that there are empty directories where binaries are
magically appear during the build. I would be much happier if we had a
real test sources there and share the large enough common bits in a
different way.

What about merging this patch as is (so I don't to keep sending it)
and then I fix all the issues you want to get fixed in this test
separately ?

I agree with the issues you raised. It took me a while to understand
how it tests different syscalls and how things magically work in
multiple directories :)

Fair enough, merged.

I believe you will apply the next patch (10/19) as well, which touches
this file and so I am starting to work on top of that now.
