+$NetBSD$
+
+On NetBSD we see ""Error sending IPC message: Message too long" due to
+the use of sendmsg with a large message body (EMSGSIZE).
+
+WebKit already uses shared memory to communicate the message body when
+the message is too large, so force it to always use this method to avoid
+encountering EMSGSIZE.
