I've just built the latest darcs so that I could use --skip-conflicts 
(it's great!).

I'm doing all my work in hashed repos locally, and my perception of the 
performance is that it's "different" to darcs-1 format repos. Some 
things are very fast: whatsnew, pull/push --dry-run. Other things seem 
to crunch my disk a lot and take a lot longer than I would expect.  For 
example, I just pushed a few patches from one GHC repo to another and it 
went like this:

Shall I push this patch? (7/7)  [ynWvplxdaqjk], or ? for help: y
Writing inventory 3 done, 30 queued. 
Writing inventory 4 done, 29 queued. 
Writing inventory 33 done, 0 queued. 
Finished applying...
Push successful.

why is it writing *all* of the inventories?  This is perhaps related to 
http://bugs.darcs.net/issue1589. I thought the point of tagginng and 
optimising is to avoid needing to write the old inventories?
