    Revert "autotools: make a copy of configuration"
    
    This reverts commit 1d0a3273d5b06a488778d23ae225225e4f28dc3e.
    
    We need the real configuration instance so that we can clear the dirty bit.
    However, we should make sure we get all our data upfront before we spawn our
    worker thread.
