The consideration is that the application fails completely on server
disconnect (because it gets SIGPIPE'd).  This was long ago deemed
unacceptable, and we aren't likely to change our opinion on that.

What disturbs me about your report is the suggestion that there are
paths through that code that fail to protect against SIGPIPE.  If so,
we need to fix that.
