This description is a bit redundant, because it repeats in prose what
the code does. I'd rather see a description of why the change is
necessary.

Thinking about it, maybe it would be good to have two separate error
codes. Keeping -EAGAIN for the case where a zero timeout was passed
doesn't sound too bad to differentiate it from the case where a non-
zero timeout was passed and it actually timed out. What do you think?
