Hi Marvin! I am sure it did not detect race immediately at least in my project, which has similar global variable race conditions, but in a more subtle way .
For example, the checking of one global variable is from an incoming message from a remote host, while the changing of the global variable is from a crontask. They have a possibility to collide, but my race build did not crash because of it yet.
