I'd love for the text plugin to clean up inlined text modules when optimized. I'd love to take a swing at this (I hacked it locally by caching the file on the node process object and fetch from that cache (unlinking the file once it's cached) but I'm seeing an issue with all require plugins. There's no easy way to add support for these plugins, I haven't looked too closely at the current code in require.js but if there's a possibility to add an hook for this that would be awesome.
Maybe this issue should be solved in require.js core first, and solved here later--but I'd love to hear your thoughts, @jrburke.
