Seems that you have missed my point. In all your examples process get killed by
SIGPIPE with *default* signal handler. However on Android system (at least on
Android 5.0 and later) dynamic linker changes signal handler for SIGPIPE to
'debugger_signal_handler' function (i suggest to read this article for more
information: https://kobablog.wordpress.com/2011/05/12/debuggerd-of-android/).
So if ps dies on Android it will not be killed by SIGPIPE, it will report to
debuggerd.
