This may be seen as a reminder of invisible concrete walls that surround the whole game of ever growing proof libraries, walls that David Matthews has continuously moved further to enlarge the playground. One day we will have to give up x86, though, and the entry to the game will be 16 GB memory. For now it should be possible to find a different example with a smaller proof object instead of Int.times_int.abs_eq above, or to tune the proof of Int.times_int.abs_eq to reduce its recorded term size -- there might be something bad elsewhere that causes the sudden increase of size.

Re: [isabelle-dev] not working
That was my mistake. I committed something I did not mean to commit because it caused too much nontermination when I tried it with testboard. Thanks for alerting me. I have just undone it. However, HOL-Proofs-ex still fails in the same manner, I have no idea why.
