title: How would I design and implement a non-blocking memory mapping module for node.js
body: <p>There exists the mmap module for node.js: <a href="https://github.com/bnoordhuis/node-mmap/">https://github.com/bnoordhuis/node-mmap/</a> </p>
  
  <p>As the author Ben Noordhuis notes, accesing mapped memory can block, which is why he does not recommend it anymore and discontinued it.</p>
  
  <p>So I wonder how would I design a non-blocking memory mapping module for node.js? Threading, Fibers, ?</p>
  
  <p>Obviously this nearby raises the question if threading in node.js would just happen elsewhere instead of the request handler.</p>
