System Information
Windows 7 64-bit
Intel HD Graphics 4000

Blender Version
Broken: 2.75 c6b042b
Worked: 2.70 19e627c

Files
adding_armature_performance.blend -- Contains an empty that adds and immediately removes 10 armature objects every frame.

Short description of error
The time it takes to add an armature object increases as the number of armatures that have been added over the course of the game increases.

Exact steps for others to reproduce the error
Open the attached file and start the game engine. Note how the logic usage starts out low but very quickly increase to very large values. On my machine the logic time increases from ~1ms to over 100ms in less than 10 seconds.

Additional Notes

The problem does not occur when adding non-armature objects
The performance hit persists as long as Blender is open. e.g. when you stop the engine and start it again without closing Blender, the logic usage will immediately jump back to its previous level instead of starting low.
The performance hit only takes place during calls to scene.addObject() when the added object is an armature. e.g. after adding many armatures, changing the added object to the default cube will result it normal logic usage. Resuming adding armatures will increase the logic usage again.
