Thanks. I've set the JinjaThreads test to run every day now, at least until the release.

JinjaThreads does terminate ;-), it just runs out of memory.

Flyspeck has always taken very long, but it terminates eventually.

It would certainly be nice to figure out where the memory is going in these computations and maybe even speed them up.

I have yet to pick up similar investigations for our seL4 proofs again. At least with the current polyml svn version, you can get more precise numbers on memory than before.
