For those who don't know, the error message is from the race detector.

Seeing this error as well. I realize the test suite that's generating this is pretty extraordinary, but it would be great to have a knob we can turn to enable a higher number.

@jarreds The race detector code is maintained as part of LLVM, outside of the Go project. That would be the place to ask.
