Found while trying to run the amstream tests.

With EGL, I'm getting various hangs and some assertion failures, some
intermittent. I also consistently see this message, which isn't otherwise
present:

amdgpu: os_same_file_description couldn't determine if two DRM fds reference
the same file description.
If they do, bad things may happen!

With GLX, things seem to just completely break:

0024:err:wgl:X11DRV_WineGL_InitOpenglInfo  couldn't initialize OpenGL, expect
problems
libEGL warning: egl: failed to create dri2 screen
libEGL warning: DRI2: failed to create screen
amdgpu: os_same_file_description couldn't determine if two DRM fds reference
the same file description.
If they do, bad things may happen!
libEGL warning: egl: failed to create dri2 screen
libEGL warning: DRI2: failed to create screen
LLVM ERROR: out of memory
Allocation failed

The errors mostly seem to be related to OOM. Sometimes I do seem to get a more
silent hang though.

This bug report is a bit vague, but hopefully at least one of these symptoms
can be reproduced. If not please let me know and I'll try to provide more
useful information.
