Granted, this export -f feature of bash needs a different, safe, implementation. But otherwise, in the context of the internet of today, yes, we'd need a completely different operating system (perhaps something based on capabilities). Unix indeed doesn't seem to be good enough for a safe internet. If we could say that there are N bugs, and with openssh and this bash bug, we only need to correct N-2 bugs and we'll be fine, then perhaps we could keep unix (and similar systems). But it just looks like it's more a systemic problem (indeed not specifically an apache bug, or a X or Y bug, but bugs emerging from the interaction between two or more components in the unix ecosystem), therefore if we don't change the fundamentals, we cannot exclude that we will keep introducing and discovering this kind of bugs again and again.
