Actually I went through and created the basis for that repo. It
contains all branches and tags in the gcc svn repo and the final
pack comes to about 600M. This has _everything_, not just trunk.
For the first time after doing such an import, I found it much better
to do git repack -a -f --depth=100 --window=100. After that initial
repack a plain git-gc occasionally will be just fine.
If you want any more information about this, let me know.
