ae, sorry, but your English  seems to be so bad so I can hardly understand what
you write (and, TBH, your Russian isn't too good either - lots of grammar and
spelling errors, but at least there are no problems with understanding the
meaning of the sentences), but if I got your point correctly, by "whether is
insufficiency of a functionality - an error?" you mean that this bug might be
treated as a "feature request" for Wine to support OpenGL (and, possibly,
Direct3D) rendering offloading into separate thread.

I can hardly believe that such enhancement - if implemented - would ever be
accepted into Wine by core devs (AJ, Henri, Stefan, name other yourself) as it
wouldn't be targeted at implementing native-specific behavior but rather
implementing a set of "clever hacks, specific to a set of the apps it is
targeted at". I might be wrong on this point, but in any case this bug remains
invalid IMO - games in question (WoW, SC) seems not to be multicore-optimized,
and utilize only one core when executed on both under native and Wine unless
there's some third party software that adds SMT optimization to these apps (GPU
drivers for native case, cleverly hacked winelib opengl.dll by your rgl patch
for Wine). 

So Wine seems to be is fine with regards to its SMT support vs. apps in
question, thus this bug is invalid. Finding a way to improve Wine/wineserver so
WaitFor* usage won't cause excessive context switches is a good and valid thing
to think about, but it is unrelated to this bug and should be discussed
elsewhere (new bug rep, wine-devel mailing list, some other place).
