A "Broken pipe" error message generally comes from the shell when it detects that a child it created has exited due to a SIGPIPE signal. So you can may be able to cause one manually by killing a child with a SIGPIPE (kill -PIPE %1 to kill the first background command).

SIGPIPE is generated by the kernel and sent to any process that tries to write to a pipe or socket after the other end has been closed.
