Is that less ugly? ;)

But yes, we are talking about in the field, so it's fairly small. But
any crash during guc loading for example would go there, I think?

We can do such a commandline. We don't have any platform-specific
commandline options today. Is that something we've intentionally
avoided, or just not needed before?
