Improving reliability and information from the large file test
Saw a couple of sporadic failures on Windows platforms. Debug output should help find what's happening. Once the fillFileSparsely test fails, there's no point in trying to read what we failed to write so maximum tested size is reset on a failed write. Reviewed-by: Markus Goetz
