Why not just do a PUT request with all the data as unmangled binary?

Well, you set it at the web server.. That stops both overlarge content-
length requests, and when the body exceeds the specified content length.
But yes, you have to provision temp file space for n files in flight x
max file size...
(I have an HTTP::Body subclass I use to stream stuff directly into
mogilefs rather than getting a temp file - code on request)...
