Bugfixes and Rails Edge

Update to Rails 2.3.1.
  (Actually, not quite. Doesn't look like 2.3.1 will be released
   today, but I REALLY want to push these bugfixes out.)
Removed bundled Rack (Rails 2.3.1 comes bundled with Rack 1.0).
Add
     config.action_view.cache_template_loading = true
  to production environment.
Fix FastCGI bug (http://rubyforge.org/tracker/index.php?func=detail&aid=24191&group_id=186&atid=783).
Fix WikiWords bug (http://rubyforge.org/pipermail/instiki-users/2009-February/001181.html).

+      # The <tt>:text</tt> option can also accept a Proc object, which can be used to:
+      #
+      # 1. stream on-the-fly generated data to the browser. Note that you should
+      #    use the methods provided by ActionController::Steaming instead if you
+      #    want to stream a buffer or a file.
+      # 2. manually control the page generation. This should generally be avoided,

+      #
+      # Two arguments are passed to the proc, a <tt>response</tt> object and an
+      # <tt>output</tt> object. The response object is equivalent to the return
+      # value of the ActionController::Base#response method, and can be used to
+      # control various things in the HTTP response, such as setting the
+      # Content-Type header. The output object is an writable <tt>IO</tt>-like
+      # object, so one can call <tt>write</tt> and <tt>flush</tt> on it.
+      #
+      # The following example demonstrates how one can stream a large amount of
+      # on-the-fly generated data to the browser:
+      #
+      #   # Streams about 180 MB of generated data to the browser.
