+// ignore-android since the dynamic linker sets a SIGPIPE handler (to do
+// a crash report) so inheritance is moot on the entire platform
+
+// libstd ignores SIGPIPE, and other libraries may set signal masks.
+// Make sure that these behaviors don't get inherited to children
+// spawned via std::process, since they're needed for traditional UNIX
+// filter behavior. This test checks that `yes | head` terminates
+// (instead of running forever), and that it does not print an error
+// message about a broken pipe.
