I was wrong: SOCK_SEQPACKET also fires a SIGPIPE, but the difference is
that when doing a write(2), it returns immediatly, while SOCK_STREAM seems 
to return when the other side dies or consume the data. Due to the way
my test case was written, I did not see the SIGPIPE with SOCK_SEQPACKET
because the process terminated too early.

This leads to another question: is it fine that write() on SOCK_SEQPACKET
is by default in non blocking mode?
