* commented out [Obsolete(....)] attributes where no replacement feature
was available: if we want to attribute code that we think needs to be
reworked, we should define a new attribute and use that instead
(together with a little tool to retrieve all the attributed code then)
* commenting out unused variables
* This is the GC.GetTotalMemory() method, which I'm guessing does not include memory used by the VM (hence the memory usage reported in top on linux would be much higher)
