Review comment:
Ah good catch. It should be a plan error instead, but I'll remove the
case.

> When there's an error on lookup or construction of an execution plan, the
> lock is accidentally held causing the worker to freeze.
> Shouldn't be user affecting, as most plans and lookups are correct without
> error, but if there's a transient GRPC issue on lookup, that might cause an
> otherwise healthy worker to deadlock.
