There's a problem with a package located on different elpa servers. I've
also updated to async 1.6 from GNU ELPA. But some days later, this was
overwritten by automatic package upgrade with async 20160108.1249 from
melpa, which does not contain the fix of Andreas.

How could I pin async to be updated only from GNU ELPA? And no, I don't
want to remove melpa from package-archives; there are other packages I'm
interested in.

Best regards, Michael.
