I think I found the bug. In LoadBitmap starting a task can fail but the state is not reset if this…
Oh, hes bool variant is the wrong one. But __sync_val_compare_and_swap should work fine. _Interloc…
Oops! I just realized that my implementation of AtomicCompareExchangeUInt32 is bogus. I shouldn't …
Thank you for the answers. Casey are you willing to implement CompletePreviousWritesBeforeFutureWr…
Just a quick note: you do not want sfence for write barriers on x64. x64's always complete writes…

In the first case, you want a store fence: In most Intel CPUs, writes are not reordered with othe…
