And, Eli, there is a Doug/Appdata/Local/ VirtualStore/Program Files/PLT/collects/scribblings/main/user directory created on my Vista machine in the Virtual Store. So, the PLT/collects/scribblings/main/user directory was apparantly created after the install. I'm not sure why it's empty, unless the directory itself is the lock.

Ah, that's very useful.

Yes, I remember that (I think that I was the one who talked about it
with you, or maybe it was someone else that I talked to), but this is
only partially related to the problem. The thing is that running a
planet setup uses the usual setup code, which is trying to verify that
all the collections to be setup are writeable by placing these marker
files -- and also using them to make sure that you're not trying to
setup the same collection twice (eg, `setup-plt -l foo foo').
One of the recent changes is that setting up a planet package is
properly reconstructing the user index, and this is somehow done in a
way that makes it (try to) lock the main/user collection.
Matthew -- is there some place in the code I can look at to see if
there's an easy solution?
