One place that this would be very useful would be for networking. Right
now, the various networking protocols send data to the child by calling
NS_ReadInputStreamToString(), then copying the string into an IPC message,
which is bad because it requires a lot of contiguous memory addresses, and
also has a fair bit of bloat from all of the copies (bug 1110596, bug
1263028).
