Lossiness isn't really relevant. Things like sticky writes work
perfectly well with data races; they don't lose anything.

My preference would be for "data_race" or something very similar
("racy"? "race_ok"?). That's the whole point -- we know the
operation can be part of a data race and we don't care.
