Not on any UNIX I know of, but that's not the point. EAGAIN is a non-fatal 
error, and we've just encountered a situation where another part of the 
code made the fd non-blocking. The old code couldn't handle this, and died. 
After the patch, it will do the right thing no matter what. This makes the 
code more resilient to bizarre OS behaviour, and to intentional or 
unintentional code changes.
