[plt-scheme] getting raw port of HTTP POST data in PLT Web Server in PLT 4.2.5?

OK, thanks, Jay.

I think I will probably have to explore the 2nd and/or 3rd options you 
mention, since this system can have multiple people HTTP-uploading huge 
files at the same time that other people's requests are running 
statistical models, etc.

I'm not sure we want to spec RAM requirements high enough to buffer 
uploads in their entirety, and I suspect that hitting swap will kill our 
performance.  Even if we had enough RAM, I'd have to look into GC 
implications of having a few 1GB file uploads buffered in RAM at once.
