    sh: Set $? to 0 for background commands.
    
    For backgrounded pipelines and subshells, the previous value of $? was
    being preserved, which is incorrect.
    
    For backgrounded simple commands containing a command substitution, the
    status of the last command substitution was returned instead of 0.
    
    If fork() fails, this is an error.
