VRAM does not empty correctly after a renderjob, which leads to an "Out of memory" Cuda error after some renderings, depending on the vram size the file uses.
It doesn't appear on every file. Can't reproduce the error exactly, but might be related to the "#frame" script in the "seedvalue" field.
When I render via Terminal on Ubuntu, it gives me the following text after a finished frame and saved file:
----
Exception ignored in: <bound method CyclesRender.__del__ of <bpy_struct, CyclesRender invalid>>
Traceback (most recent call last):

Further working on a project with test renderings or preview rendering is impossible without restarting Blender.
This error appeared with 2.74 and is still present with 2.75 RC2.
