I just show you the way of finding such cases, I already say I don't have 
much time to dig out real one. It is you who must prove that your addition 
not change anything or not violate POSIX. Because there is strong 
suspicion that you violates POSIX quote I already mention.

I.e. look in the fo_read() chain and see which errors are skipped now. 
Even if you don't find such ones, it may simple mean that resid==0 check 
was placed preliminary in our old code, and it is old code which needs to 
be fixed.
