 I recently discovered a possible issue with the OpenLayers.Util.isArray
 -function. If a custom array is used that inherits from the standard
 array, the isArray will return false.


 {{{
 var MyArray = function(){
 };
 MyArray.prototype = new Array();

 var anArray = new MyArray();

 anArray instanceof Array; //true (the 'old' behaviour of OpenLayers)
 OpenLayers.Util.isArray(anArray); //false
 }}}

 Tested in FF 3.6.15 and IE9.
