The SIGPIPE is sent when you attempt to write to the socket, not when
the kernel receives the RST.  So in your example, the timeline looks  
like:

client			server
------------------------------
                         listen
connect			
                         accept
                         abort
         <-----------FIN
write
sleep
      |  'hello' -------->
      |  <----------- RST
write: SIGPIPE


That is a pretty lame diagram but I hope it clarifies things.

FYI, this is a behavior of the underlying socket abstraction, not
something particular to Ruby.
