[isabelle-dev] Nonterminating AFP build

[Lawrence Paulson]

It has no timeout, sorry, that was my fault. Now set to 300 seconds.

We don’t need a global timeout, but why not a default timeout? We could set up to the median runtime. Actually I think our typical value of 600 seconds is much too high, considering that a loop in a common library could make dozens of entries run forever.
