I'd like to use fread and fwrite in place of File.rawRead and
File.rawWrite which force the creation of an array where I'd
rather specify a buffer location and length. I'd like to do this
using a File object but the handle for the C stream is a private

Until pretty recently the compiler was a little picky about the
