Thread sanitizer doesn't understand fences. It seems relacy is the only one that does. If anyone knows how to make relacy run a somewhat fair scheduler please let me know - it told me a server thread that waited for work never made any progress, but it also never gave a client thread any cycles to submit work so that wasn't very informative. (edit: just occurred to me I can probably fake it adequately by having a yield that makes the current thread start playing the role of the other service, coroutine style)
