I am not familiar with this code but there are many options to choose from.
A Callable<Void> (this throws an Exception), Lucene's IOConsumer<Void>, adding
an IORunnable similar to IOConsumer, IOFunction or IOSupplier we already have..
I would opt for an IORunnable, if it's something used only there. An IOCallable
could look like this:
```
interface IOCallable<T> extends Callable<T> {
@Override
public T call() throws IOException;
}
```
narrowing the type of exceptions thrown to only IOException and keeping an
option to return something from the inside, at the same time allowing
submission of such blocks to plain Java concurrent infrastructure? Just a
thought.
