    from the same random seed. This is quite possible the cause of stitching
    failures. From the File::Temp man page:
    "If you are forking many processes in parallel that are all creating
     temporary files, you may need to reset the random number seed using
     srand(EXPR) in each child else all the children will attempt to walk
     through the same set of random file names and may well cause
     themselves to give up if they exceed the number of retry attempts."
