tempfile.rb seems to have a broken unlink function
When using tempfile on Ruby 1.8, unlink does not close the underlying file, which is useful on POSIX systems to stop other processes from accessing the temporary files. Similar suggestion is available in the comments for Tempfile#unlink on Ruby 1.9's tempfile.rb but there, the file gets closed before being unlinked, and thus you cannot access it any more.
I'm not sure if the change in behaviour is wanted or not, but this at least seems to break Rack (from which I extracted the attached testcase). Either the suggestions should go, or it shouldn't close.

I just want to be clear on what you mean; you're saying the Tempfile should still be usable (not closed) after Tempfile#unlink has been called, right?
Works for me using a 1.9.2dev build from 2010-04-24 (6 days ago). Maybe something needs to be backported to 1.9.1?
