Which leads to the interesting question why the subrepos are pulled in
that order...

I can optimize that with

diff --git a/mercurial/subrepo.py b/mercurial/subrepo.py
--- a/mercurial/subrepo.py
+++ b/mercurial/subrepo.py
@@ -144,7 +144,7 @@
                 debug(s, "prompt remove")
                 wctx.sub(s).remove()

-    for s, r in s2.items():
+    for s, r in sorted(s2.items()):
         if s in s1:
             continue
         elif s not in sa:

It will then go like this on Windows:

  $ hg clone http://hg.gerg.ca/allextensions
  destination directory: allextensions
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 10 changesets with 20 changes to 6 files
  updating to branch default
  pulling subrepo Artemis from http://hg.mrzv.org/Artemis
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 55 changesets with 108 changes to 47 files
  abort: The directory name is invalid: C:\Users\adi\hgrepos\allextensions\Artemis\aux

(Ok. Purpose #2 accomplished: I started playing with subrepos :-)
