some more code from mrieker for system threads, give up of all the other mono dependent theading models only availble for linux (and possible not all platforms). This only has impact on micro-threading switching, and this only happens on long events and only every 60ms, aditionally we do remove a totally extra set of threads (that could grow in a uncontroled way on win) and their hanshake with main ones. This may of course be even more broken now :P
