I assume there's a reason you're reading the input file by line instead
of just copying it using larger fixed-size blocks?  Perhaps you have in
mind some kind of line-based filtering or processing eventually?

Because for copying a file, using a large, fixed-size block will work
much faster. Not to mention the code will be simpler. For example:

	auto inputFile = File(inputFilename, "r");
	auto outputFile = File(outputFilename, "w");

	enum bufferSize = 8194;
	inputFile.byChunk(bufferSize)	// read input in blocks of 8194 bytes
		.copy(outputFile.lockingBinaryWriter); // copy each block into output file
