+# == Tempfile (Patch)
+# Tempfile has a horrible bug where it causes an IOError: closed stream in its
+# finalizer, leading to intermittent application crashes with confusing stack
+# traces. Here we monkey patch the fix into place. You can track the bug on
+# ruby's redmine: http://redmine.ruby-lang.org/issues/show/3119
+#
+# The patch is slightly different for Ruby 1.8 and Ruby 1.9, both patches are
+# included here.
