Read() and write() do not preserve message boundaries so you cannot
guarantee to read 8193 bytes just because you wrote 8193 bytes.

This is an error in your program:  The read() succeeded and returned
4992 bytes.  The child then exits

>main send len [-1] failed: Socket is not connected

Which leaves the socket unconnected so the parent (correctly) receives
an error.
