Valgrind warning in wined3d/swapchain.c in IWineD3DSwapChainImpl_Destroy

[Dan Kegel]

Hi Stefan,
you seem to have been in this code recently, could you have a look?
This is a somewhat flaky error that happens about 80% of the time
under heavy load on my quad core box.
(This is valgrind's xml output format, it's pretty fluffy, sorry.)

Thanks,
Dan
