Why would you want to do that?

Well, it depends a bit how you are planning to deal with wined3d_cs_emit_*() calls on the command stream. Just appending at the end of the stream wouldn't be a good idea here, because its executed after all the contexts are already destroyed. Dispatching immediately might work, but is a bit dangerous because there is currently only one buffer, and you are replacing the content while the previous command is still active. Feel free to ignore if you are planning to use a different solution for this problem.
Best regards, Sebastian

The idea is to dispatch calls immediately, yeah. Strictly speaking the patch that introduced wined3d_device_delete_opengl_contexts_cs() depends on another patch that isn't currently upstream to properly handle that case in wined3d_cs_st_require_space() and wined3d_cs_st_submit(), but I only realised that after submitting the patch. In practice it shouldn't matter in this specific case though, since the CS packet's contents are consumed before the new packet is emitted.
