I've actually fixed the underlying implementation that was causing failures in another ticket, and frankly, I don't want to fix this. I don't think that that either the initCall site or resolveOrDie (which we rely on here) should be in the business of catching indeterminate exceptions, and unless we do so, it makes very little sense to try catching any at all.
