Its documented. From the manpage that I read several times by now:

Wait for preceding jobs in the job file to exit before starting this one.  
stonewall implies new_group.


Somehow despite my reading of manpage, README, HOWTO I came to the thought 
that it tells fio to wait for the current job to finish, thus I had the 
stonewall options misordered.

I expect that it works exactly as you said and try it this way. Instead of 
omitting the last stonewall option in my iops job file I could omit the 
first for the first job. Cause the first job does not need to wait for a 
previous job.

Thanks,
