That deletion was apparently in the release25-maint branch where this bug
has been fixed in order to avoid the test case from allocating 8gb on 64bit
hosts where it wouldn't need to raise a MemoryError (
http://bugs.python.org/issue2137).  However it looks like it was never
committed to trunk.  (release25-maint r60793 has a lot of fixes)

I'm looking into merging the fixes into trunk.

Martin, since you committed 60793 in Feb, any others like this that need
merging from release25-maint to trunk off the top of your head?
