Similar problems occasionally happen with SIGPIPE. There are apps[1]
that spawn processes with SIGPIPE set to SIG_IGN giving unexpected
results, i.e. child processes that still try to produce output
(getting EPIPE on every printf, but who checks printf errors?) even
if the pipe-reader (e.g. their parent) is long gone.
Ciao, ET.
[1] i.e. KDE had this bug - don't know if it's still there.
