> The Kafka codebase includes a number of instances where we do `catch t: 
> Throwable` where we should really be doing `catch NonFatal(t)` or `catch 
> NonControl(t)` where `NonFatal` is part of the standard library and 
> `NonControl` is something like:
> {code}
> object NonControl {
>    def apply(t: Throwable): Boolean = t match {
>      case _: ControlThrowable => false
>      case _ => true
>    }
>   def unapply(t: Throwable): Option[Throwable] = if (apply(t)) Some(t) else 
> None
> }
> {code}
> We can also use `NonControl` to replace cases like (it's more concise and has 
> the same behaviour):
> {code}
>   case e: ControlThrowable => throw e
>   case e: Throwable => ...
> {code}
