So If I understand what your saying, EAGAINs or partial writes are 
interpreted
as fatal errors. This confuse me. EAGAINs or partial writes are flow 
control
issues not fatal errors. Just like on the client side, shouldn't the
thread sleep until there is room? Closing down the socket seems a
bit drastic... Or am I missing something?
