Could you clear up what you mean *exactly* here?
Do you mean 1) that any system that provides some kind of timeout (in
terms of wall time or another measure) for evaluation is broken, or that
2) a build setup that runs into such a timeout is broken? That's a big
difference.

_I_ think that doing 1) is reasonable to keep a IDE like Creator
responsive. And of course, you report an error and fail the build when
that happens. A message stating where the issue occured would of course
be very helpfull.
