29 * Test read/write of a 10M block of data in a single operation.
30 * Uses an in-memory archive with a single 10M entry. Exercises
31 * archive_read_data() to ensure it can handle large blocks like
32 * this and also exercises archive_read_data_into_fd() (which
33 * had a bug relating to this, fixed in Nov 2006).
