I was doing some benchmarking, so I booted with nosmp and am running lwm
instead of gnome, and was surprised to find that Mass Effect 2 demo
aborts before it gets to "press any key"!  
+relay makes the problem go away, but +synchronous,+d3d doesn't.

The log shows
trace:d3d:WineD3D_CreateFakeGLContext getting context...
XIO:  fatal IO error 11 (Resource temporarily unavailable) on X server ":0.0"^M
      after 4062 requests (4060 known processed) with 0 events remaining.

Adding a couple TRACE() statements shows the abort happens between the two
lines
    DescribePixelFormat(ctx->dc, iPixelFormat, sizeof(pfd), &pfd);
    SetPixelFormat(ctx->dc, iPixelFormat, &pfd);

Sadly, adding +wgl makes the problem go away.

This was with an nvidia gtx 560 ti and drivers 270.41.06.
