Module host_data 

Named data a host supplies on request, for builds that ship large application data (fonts, archives) beside the program instead of inside it. An application asks for a name each time it needs the bytes; a host that can fetch drains the requests, fetches each, installs the bytes or a failure, and relayouts its surfaces so the application asks again. Builds that embed their data never ask, and a host that never drains leaves every request pending.
