Nice, looks pretty useful! I think the default execution time should probably be less than 60 seconds. Most simple programs that people run on this kind of site should have an execution time of less than a second, so ~10 seconds should certainly be enough by default. This would free up some resources on your end and would inform people more quickly that they may have an infinite loop in their code.
