Overview

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: 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.
