The reason I want to wrap existing memory in a raw vector:

• R does not expose handling of "connections" within C
• In C, I have existing memory to write to an R connection
• I have to alloc a RAWSXP of the appropriate size & copy the memory into it
• Then call out to R (from C) to the function writeBin()
• And writeBin() is just going to unbox this & use the raw memory

So a 'fake' SEXP header would save a bit of unnecessary overhead & copying

And there is lots of data to write!
