I'm not a native speaker. I'm afraid I just don't appreciate such
nuances.

I used 4 to match the commit message, which incidentally is the result
of a prior suggestion from you. Sorry for not being consistent then.

As for numbers... I don't have any, but I probably mentioned already
that I can run a copy of Fedora on top of a kernel with POSIX timers
disabled and none of the warnings about those disabled syscalls are
triggered. So if my Fedora usage doesn't need them, we can infer that
the number of embedded systems also not needing them might tend towards
a high percentage. But let's be conservative and say "some".

Thanks for your review.
