"made his suggestion" is probably a wrong statement from me, looking
back the emails, Miguel was simply talking about we should document this
and his assumption that `fsleep()` should inherit the behavior/semantics
of msecs_to_jiffies().

But yeah, I still suggest doing it differently, i.e. panic on negative
or exceeding i32::MAX milliseconds.
