It's possible to compile the calculation code to work in batches -- for example, http://wry.me/hacking/Turing-Drawings/ http://wry.me/hacking/Turing-Drawings/ which compiles a 2d Turing machine into an asm.js function parameterized by how many steps to take in an uninterruptible batch. Another example of batching for responsiveness: http://wry.me/hacking/powersp.html http://wry.me/hacking/powersp.html It's also easy for me to suggest more work for you!
