These are two extremes. What we're looking for is tools that find bugs.
I've brought this up before so I apologize for repeating myself (I've
explained this to the tsan guys also), but I'd really prefer if tsan was
rewritten entirely to be like Microsoft Chess. Infinitely more useful, and
all bugs are real (like valgrind/asan).
