Each iteration reads a new line from PORT, an input port on a text file.
The file is created by guix-daemon and has a format like this:
FILE
DERIVER
NUMBER-OF-REFERENCES
REF1
...
REFN
where each FILE is a store item (see store-copy.scm for details).
Here we only care about FILE and REF*.

I think it does! :-) It wouldn’t hurt to add a call to
‘delete-duplicates’ though.
