+<para>This is useful in case the underlying source data for the tiles changes (e.g. OSM data is continually evovling).
+ &appname; normally has no way of knowing when the data has changed, so this simple timeout method is provided to maintain consistency of the tile images.</para>

+<para>
+ The number of threads to use for Mapnik rendering tasks.
+ By default the value is set to the 1 in case of any multi-threading rendering code chain crashes.
+ Otherwise trying setting the value to the number of the CPUs of the system minus one (so as not to overload the system), in order to minimise the overall rendering times.
