Tried this on my BCM4710 MIPSEL OpenWrt/Debian (problematic
cache-suspected history due to possibly related USB-audio lockups),
/dev/sda3 ext2 on an USB stick, no errors here, even when increasing tenfold
to 2560 and adding a sleep(2) in between.

Will investigate these things for real sometime later.
