Yes, I implemented a timeout of just a few seconds (7s, I think). It's short so that it doesn't take too long to test with all the compiler versions. I actually tested that the template recursion is limited (500) but not CTFE (at least in my check of that it was still executing after about 15 minutes). That's also why there is already a test called "infinite CTFE", I wanted to make sure that a DOS could not be achieved with a single test case (but is still easy at the moment, since I don't have rate limiting ;))
Ah, right - CTFE is indeed not time limited, only has a recursion limit I think. A limit imposed directly in the compiler would do more harm than good, so it's perfectly understandable.
Assuming you're invoking DMD as a shell command - make sure no user input ends up in the shell command, like the name of the test etc.
