Yep. Which also means that whatever advantages they bring, we can probably get in a traditional system call API if designed the right way.<p>There was a highly interesting research project along these lines: <a href="https:&#x2F;&#x2F;arrakis.cs.washington.edu&#x2F;" rel="nofollow">https:&#x2F;&#x2F;arrakis.cs.washington.edu&#x2F;</a><p>The Arrakis paper also show how much overhead the traditional UNIX architecture is (contrary to the authors assertions) for many popular workloads. It is now merged back into the project it was forked from (Barrelfish) which in itself is a very interesting research project. Well worth studying for those that don&#x27;t believe UNIX is the last word in OS design.
