Thanks Shawn, I applied this and the previous. I changed a few things in
later commits, the primary one being setting a valid low value for
header_interval. If you set eg 8 which is smaller than the verify_header
structure, fio would segfault. Plus the value isn't really legal, you
have to leave room for actual dat.
