It's probably time we took another look at the options, that's all.
Darcs still doesn't really support the development model we'd really
like though (long-lived branches and lots of merging). On the other
hand, darcs is supporting our other workflows reasonably well - for
example pulling fixes into the stable branch is usually nice and easy.
We still have problems with darcs on Windows - e.g. see Simon PJ's
recent bug report about a random "permission denied" failure that left
the repo in a trashed state.

I want to try out hashed again. Last time I tried it, there were
performance problems, but it turned out that hashed repos were using a
global cache by default, and my home dir is NFS-mounted. There was a
problem with turning off the global cache IIRC - has that been fixed
now? I'd really like to either disable the cache, or point it to
somewhere locally mounted.
Does the cache still put all its files in one directory? That was one
source of the performance problems, I think.
