Because in CliClient.resume() we don't account for the case, when there is an exception in one of the async processing stages:

void resume() {
	...
	try {
		client.startAsync(state -> {
			printer.ifPresent(p -> p.print(state));
			if (!options.shouldSeedAfterDownloaded() && state.getPiecesRemaining() == 0) {
				runtime.shutdown();
			}
		}, 1000); // <-- CompletableFuture.w

Hi, First and foremost, I think this is a great start at making something really simple and effective. Thank you!!

Let us say we have

const query = `SELECT ${distinct}, ${columns} FROM ${table} ${innerJoins} WHERE ${where}`;
(Where distinct, columns, table etc are their own strings made up of other
