"with some attributes set"

However, since this is documenting the interface it probably shouldn't specify
implementation details.  So I'd just say "SocketPair() returns a pair of socket
FDs suitable for using with IPC::Channel".

+  // (such as non-blocking mode). This returns raw FD #s for the pair, which
+  // allows us to pass file descriptors between processes (such as between
+  // a plugin process and the browser process) before actual initialization
+  // of IPC server Channel instance.
