Another strategy is to throw SIGPIPE at the relevant processes:
* Con: it is usually expected upon write(2) not read(2) et-al.
- At least for write(2) the semantics is natural -- no more writes
on this file descriptor.
- Kills the offending process by default.
- Process may catch it in a signal handler (easy to write some
global cleanup + exit code)
