Python can now run operators with their own context (data context).

Browse Source 
The aim of this is to avoid having to set the selection each time before running an operator from python.

At the moment this is set as a python dictionary with string keys and rna values... eg.

C = {}
C["active_object"] = bpy.data.objects['SomeOb']
bpy.ops.object.game_property_new(C)

# ofcourse this works too..
bpy.ops.object.game_property_new({"active_object":ob})

# or...
C = {"main":bpy.data, "scene":bpy.data.scenes[0], "active_object":bpy.data.objects['SomeOb'], "selected_editable_objects":list(bpy.data.objects)}
bpy.ops.object.location_apply(C)
