3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ben Hutchings <b...@decadent.org.uk>
This reverts commit c5ee58688baa98bc3a4f6095a1acf6fd7fd9e967,
which was commit 201e72acb2d3821e2de9ce6091e98859c316b29a upstream.
Herton Ronaldo Krzesinski pointed out that the race condition this
dealt with does not exist in 3.2.y.
