I'm working a a password recovery program and make use of various combinatorics libraries (Algorithm::Combinatorics, Algorithm::Permute, Set::Product). Depending upon the input, the program can run for days or weeks. I often wish that I could restart a job from a saved state or distribute the processing to multiple machines, but none of these libraries provide access to their state. In fact, I couldn't find a combinatorics library in any language that does. I would think this is not an uncommon task. Is it not easy to accomplish or not possible?
