Older GLib versions (< 2.32, e.g. the ones shipped with CentOS 5 and 6, SLES11, Debian 6) need an explicit initialization to make things thread-safe. RRDTools didn't do that, so the Check_MK Micro Core and rrdcached crashed randomly on those systems. Now we make sure that GLib is properly initialized before calling into it.
