Alexey was right, stable releases are on a separate branch. Well, actually
VBox 3.2.2 was the last release which had a related SVN revision in trunk,
namely r29998.

We also had a check of the time which is used for a Windows 7 installation
and were not able to observe any differences between 3.2.8 and current trunk.
We tested this on an Intel Xeon E5345 (2 x 4 cores) on Windows Server 2008.
