Basically, I'm going back to the old git way of having each > submodule have its own .git directory, rather than having it have a > .git file with a 'gitdir' entry. Am I understanding this right? Basically. The initial clone can still use --recurse-submodules. When you create a new workdir you'd create new workdirs for the submodules by hand. A 'git submodule foreach' command in the initial repo can take care of the `parse-.gitmodules` part.

If concurrent fetches cause trouble then I'd consider it a bug (it's not too different from multiple concurrent pushes to the same repository, which is a very common thing to do), but I haven't looked carefully into whether such bugs exist. Hopefully someone else can chime in.
