I like option 0. It can't be incumbent on us to provide defenses
for every bug in every piece of software that we depend on ...
especially not edge-case bugs like this one seems to be.

If we had a surplus of time and people-power available, maybe it
would be reasonable to do something about this. But you know as
well as I do how horribly short we are on both.
