  | this seems to still miss the case kre was talking about:

It does, but there also needs to be a limit somewhere (unless we add
more complicated code - which we could do for unusualk cases),

In practice soming near this limit is very rare, and as long as we
have some documented (and ideally posix approved) behaviour, it should
be OK.

My only issue currently is that rlimit.max can be reduced as well,
so I think we should have a value that we always permit, regardless
of that limit (ie: max(rlimit.max, 1000) or something).
