The nouveau graphics driver's support for multithreaded OpenGL is buggy at least up to (18.2.8) so that any Wine test that performs multithreaded OpenGL accesses freezes, crashes the Mesa stack and eventually freezes the whole computer. Typically the first such test is d2d1:d2d1. The relevant tests have a --single option but WineTest neither knows which tests accept this option, nor whether it is needed for the current host. The WINETEST_NO_MT_OPENGL environnement variable can be set on hosts that need it (such as the cw2-gtx560 box) and is automatically inherited by the relevant tests thus working around this issue.
Works for me. If you're not attached to the name though, could I suggest WINETEST_NO_MT_D3D (or perhaps simply WINETEST_NO_MT)? OpenGL is somewhat of a wined3d implementation detail, and this environment variable would also affect the tests running on Windows or with the wined3d Vulkan backend.
