Who agreed to that?  Your example is entirely unconvincing --- deadlock
is very far from being the only failure that will recur indefinitely,
if an app writer is so foolish as to code an indefinite retry loop.
Any simple illegal-data-value error will act the same.

I do not think declaring by fiat that certain types of errors abort the
whole tree is acceptable from the user end or reasonable from the
implementation end.
