New IPaths are stored in an IInterfaceList (call it GarbaegeList) - * to artificially increase the ref-count of the newly created object. - * This keeps the object alive when FPC's temporary variable comes to the end - * of its lifetime and the object's ref-count is decremented - * (and is now 1 instead of 0). - * Later on, the object is either garbage or referenced by another variable. - * - * Look at - * MyPath := Path('SomeDir/SubDir').GetParent() - * - * (1) The result of Path('SomeDir/SubDir') is garbage as it is not used anymore. - * (2) The result of GetParent() is referenced by MyPath - * Object (1) has a reference count of 1 (as it is only referenced by the - * GarbageList). Object (2) is referenced twice (MyPath + GarbageList). - * When the reference to (2) is finally stored in MyPath we can safely remove - * (1) and (2) from the GarbageList so (1) will be freed and the ref-count of - * (2) will be decremented to 1. - * - * As we do not know when it is safe to remove an object from the GarbageList - * we assume that there are max. GarbageMaxCount IPath elements created until - * the execution of the expression is performed and a reference to the resulting - * object is assigned to a variable so all temps can be safely deleted. - * - * Worst-case scenarios are recursive calls or calls with large call stacks with - * functions that return an IPath.
