    We've seen failures like this:
    
        objc[57662]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
        objc[57662]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
    
    I think this is due to forking off some background processes during
    `hg update` or similar. I don't have any conclusive proof this is the
    fork() call that's to blame, but it's the most likely one since the
    regular `hg update` codepath uses the other fork() invocation (via
    workers) and we don't get this report from non-Google macOS users.
    
    Ugh.
