Comment:

 Looks like I committed this a while ago, but forgot to close the ticket:

 {{{
 commit 3122a9f7ab30f1eb0d70b50cabf29e6da2e20e5e
 Author: Simon Marlow <marlowsd at gmail.com>
 Date:   Mon Jun 11 12:21:43 2012 +0100

     add cloneTChan (GHC Trac ticket #6157)
 }}}

 I just added a test for good measure.
