We seem to have somehow lost this bullet point that was in 9.3.3.2 of 08-007:

"Each record shall be read or written by a single image. The processor shall 
ensure that once an image commences transferring the data of a record to the 
file, no other image transfers data to the file until the whole record has been 
transferred."

I don't see a problem here.
