update: fix spurious unclean status bug shown by previous commit
The crux of the problem is:
- the dirstate is corrupted (the sizes/dates are assigned to the wrong files)
- because when worker.worker is used with a return value (batchget in
merge.py here), the return value when worker.worker effectively parallelizes
is permuted
- this is because worker.worker's partition of input and combination of output
values are not inverses of one another: it split [1,2,3,4,5,6] into
[[1,3,5],[2,4,6]], but combines that into [1,3,5,2,4,6].
Given that worker.worker doesn't call its function argument on contiguous
chunks on the input arguments, sticking with lists means we'd need to
know the relation between the inputs of worker.worker function argument
(for instance, requiring that every input element is mapped to exactly
one output element). It seems better to instead switch return values to
dicts, which can combined reliably with a straighforward restriction.
