   I think this needs a bit more work. Will follow up with a more detailed review in a few days, but the basic points are:
   
     - no tests
     - not all FS implementations actually support recursive deletes well (object stores are slower in recursive delete than file-by-file delete)
     - the extracting of shared keyed state handles could use a different approach
