Unfortunately, as is most always the case of negligence instead of some particular language features:

“A commission attributed the primary cause to general poor software design and development practices rather than single-out specific coding errors. In particular, the software was designed so that it was realistically impossible to test it in a clean automated way.“

Ergo, concurrency doesn’t kill people, people do.
