Yes, git-svn by itself cannot handle Twisted's repository both because
of the repository layout that is different from what it expects, but
also because if git-svn tries to mirror a repository with a large
number of branches all at once it slows to a molasses-in-January
crawl.

The solution that I've come up with is to use git-svn to create a
separate Git repository for each branch, and then git-push that branch
into a central Git repository.  This does burn *a lot* of disk space,
but only one person needs to do it - everyone else can clone the
central repository.  The initial setup takes a while, but subsequent
runs should be relatively fast.

You can see the converted repository I'm building at:

https://github.com/jcollie/twisted

It's still in the process of building up so not all the branches are
there yet.  I've put the script that I'm using here:

https://github.com/jcollie/twisted-svn-convert

One feature that I'd like to add before calling this final is
converting SVN usernames to "proper" names/email addresses like Git
prefers to use.

I use a similar script to mirror the Asterisk SVN repository with some
good results:
