Actually I don't know. I'm don't know a lot about Windows support in git at
all.
I created the pipe, because the current vcs-svn/* code requires it for
importing svn dumps. I can't explain yet why it requires it.

stdout is connected to the parent, while the new pipe connects it's two
childs..
It works.

Good point.

I think whenever the remote helper uses some specific commands of fast-import
it needs the cat-blob-fd to read feedback, but I haven't digged into that
yet..
