I have a test (~100 loc) that fails immediately on 64-bit Linux without resorting to fiber migration. Using the FiberFixes branch allows it to pass. If you're interested I'd be happy to provide.<br>
Also, will I asked before but never got an answer: Is there any plan to merge FiberFixes with the the trunk?<br>

Yes, please provide. I know there is still an outstanding issue with std.parallelism, but I can't reproduce it so there's not much I can do about it. I'll take any help I can get<br>
