Actually, we cannot assume that using "-dx9single" is supposed to disable ALL
multithreading in GW2 - apparently, this is not the case. The GW2 wiki
describes the flag as

"Enables the Direct3D 9c renderer in single-threaded mode. Solves issues with
running in Wine, but may be slower."
(http://wiki.guildwars2.com/wiki/Command_line_arguments).

But I bet the game engine uses several threads (resulting in load on several
cores, in the best case) for more aspects than just rendering. Most likely, the
flag does not disable those.

Well, from what you say, it seems possible to find a "clean" solution that is
not just a hack... but it also seems like that involves a lot of work and deep
changes to wine. Do you think a general fix for this can be created?
