New submission from Lorenz Mende <lorenz.me...@gmail.com>:
The test suite fails with the first tests (I assume 1st call of getloadavg of
WindowsLoadTracker).
Traceback (most recent call last):

##########################################################
The windows 'typeperf "\System\Processor Queue Length" -si 1' command unluckily
returns an string with an umlaut which leads to the Decode-Error. This comes up
because the <counter> for the typeperf is location dependend. (In german the
counter would read \System\Prozessor-Warteschlangenlänge)
I see two possible solutions to this issue.
1. Raising an exception earlier on creation of WindowsLoadTracker resulting in
the same behaviour as if there is no typeperf available (german pythoneers
would have a drawback with this)
2. Getting the typeperf counter correctly from registry
(HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Perflib\CurrentLanguage, described here
