In my particular case this is about DSA-signatures in Thunderbird with Enigmail. These are very slow to re-check for messages with large attachments. I have a low-end 25-W PC only some notebooks and other embedded devices may also be affected by this problem. When there are 3 to 4 compute-cores available and only one of them is used for crypto-operations, obviously things are going slower than they could be. Concerns about parallelizing crypto-code are generally understandable, because people don't want to give away code-integrity and -safety for speed and auto-parallelizing does not seem recommendable. In spite of that, things should not deliberately be additionally worsened by double-checking without any real need to do so.
