In context the you can see the code at

Honestly, I have no idea why the direct append isn't working. In 'sink'
the code opens ofd with an open. I had initially tried doing an lseek to
the end of the file which didn't work. Then I tried open the file with
O_APPEND and that didn't work either. I think the issue is in atomicio6
but modifying that would be more intrusive than I would like for this
