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.
