--- Comment #84 from Sebastian Lackner sebastian@fds-team.de --- For those waiting on a fix: I actually started working on this several months ago, but when I realized how difficult it is to get such a huge feature upstream, decided to defer working on it. Lot of people, including me, already have trouble to get much easier patches upstream.
This was before we started with our Staging tree idea. Back then I already wrote over 3k lines of code, which implement the most important features for worker and timer functions. Most of the threadpool IO stuff is still missing or at least untested.
I decided to clean it up, and I hope that I'll be able to add the first version to Wine-Staging until the next release 1.7.36. It might not be sufficient for the high quality standards of upstream wine though, and a lot of tests are also still missing. I'll update this bug report when I've added the implementation.
