Feature to constrain computation time?

[Szabolcs Horvát]

Does Sage have a feature to constrain computation time? Suppose the function f() takes a long time to run. I am looking for a way to run it *for at most 5 minutes*. If it finishes by then, I'd like to have the return value from f(). If not, it should communicate that clearly, and the system should be ready for the next computation.

For those familiar with Mathematica, I am looking for something similar to its TimeConstrained[] command.

You could use `alarm`, see

I think it has. But what if you just use timeout from command line? I.e.

timeout $((5*60)) ./sage my_script.sage
