But you can tell that a program didn't finish after a given threshold (a week or so) without violating Turing's laws.

In theory it should be possible to approximate O(n) by benchmarking for increasing n and using numerical methods to interpolate the gotten data.

In praxis a human should define what exactly "n" is, the accuracy of the interpolation ( O(1) and O(log log n) can look very similar ;) and when to stop testing... with "enough" time for testing you'll certainly get a result...
