You would pretty much need to fill up the socket send buffer before it
even thinks about failing.

You might consider doing a test to see if attempting a non-blocking
read on the socket yields a pending read.  For blocking reads, this
would result in an EOF if the client has dropped the connection, but
I'm not sure what will happen w/ the non-blocking reads on your system
without running a little test.
