> 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.
