It may be worth noting that nearly all well-written UNIX applications should set the disposition of SIGPIPE to SIG_IGN. SIGPIPE is a hack. It exists only to terminate poorly-written programs that could otherwise block a pipeline. See Bach, The Design of the UNIX Operating System; if memory serves, Bach quotes Dennis Ritchie on this point. SIGPIPE was introduced because some poorly-written programs did not check the return code from write.[1]

This is excellent advice. In principle, I am in complete agreement. We should not write code that depends on this artifact. We should treat it as deprecated. 

However ... ;-)  

It's probably also true that there is a lot of code that depends on it. True to form for "deprecated"
