If this is removed, maybe we should remove similar checks for C++ listeners to
stay consistent.

Is there any way to get the best of both worlds, i.e. not crashing on stack
overflows within the listener but still handling exceptions within listeners? We
don't necessarily need to disallow them, as long as they're not silently
swallowed.
