 Reading the config file should occur only once, well per appdomain.
 Are you using multiple appdomain ? 4 by any chance ?

 Nope, only one.

+I can't duplicate the multiple load in a single appdomain. Could the 4
+times occurs only for the last part of the bracktrace ? (e.g.
+InternalEnsureCapacity and Append ?)

+I don't have heap-buddy installed but I'm curious what results would
+this sample code produce :-)
+
+In the mean time I'll update the code to use the newer small-XML
+parser (and a TextReader) and see the changes in mono allocation profiler.
