shortened results from windows and linux execution

When creating a new average counter in a new category, there seams to be a problem with the base-counter.

Test case:
Source from
http://msdn.microsoft.com/en-us/library/system.diagnostics.performancecounter.aspx

Works good with Windows (executed with administrator priviliges to be able to create new categories)
For linux it is required to replace the two lines:
>if (SetupCategory())
>            return;
with
>SetupCategory();

otherwise, the programm will only create the category but not continue.


Does not work with linux.
returned values are wrong (infinity instead of the average!)

(shortened Version) of the outputs (windows and linux) attached.

It seams that the base counter is not increased correctly. Therefore the measured results are wrong (infinity)
