[Mongrel] Uploading Large (100mb+) files

If you're using Rails with Mongrel, file upload currently sucks. If you have
two mongrels running (say) and two users upload two large files, your entire
app will be hung just serving those requests. This is because Rails can't
run safely multi-threaded, and it's not Mongrel's fault.
An upload only Mongrel could (and should) be written in a framework other
than Rails. Both Camping and Merb are good choices. In this instance you
don't need many mongrels since even 1 can simultaneously serve many file
uploads. So you'll ideally have 1 server where you have one or more mongrels
running your file upload app, and use that to accept uploads. This is what
we do at SlideShare: we have a custom Camping app to accept file uploads.
Your frontend webserver or load balancer would redirect all requests to
/upload (say) to your uploader mongrel running at it's own port. And all
other requests can be served some other way. We do this through lighttpd
