Although this looks weird and it's not what I would expect, it's not a
POSIX violation as far as I can see. The system is required to send a
SIGPIPE signal in this case, but it is not required to deliver the
SIGPIPE signal before 'write' returns with errno == EPIPE. Arguably it's
a bug in GNU/Linux anyway.
Your patch is a step in the right direction, but needs a bit of cleanup;
I plan to look into it more carefully later. Thanks!
