This must be tested in some way. I can see this potentially
breaking something.
Especially this is true because ide_complete_rq() does it's
"complete whole request right now" logic for error <= 0.
Borislov/Tejun, can either of you test this code path with this
change applied? I'd very much appreciate it.
Thanks!
