Efficient cloning from svn (with multiple branches/tags subdirs)

Hello,

I'm trying to clone an existing subversion repository (Restlet: 
http://restlet.tigris.org/source/browse/). I'm using Git 1.6.5. The 
layout of the project is like this:
   trunk/
   branches/1.0
   branches/1.1
   tags/1.0/1.0b1
   tags/1.0/1.0b2
   ...
   tags/1.0/1.0.1
   ...
   tags/1.1/1.1.0
   tags/1.1/1.1.1
   ...

Therefore, I've tried to use this (with and without '-T trunk', but that's a separate problem):

   git init
   git svn init --prefix=svn/ -t tags/1.0 -t tags/1.1 -t tags/1.2 -t 
tags/2.0 -b branches/1.0 -b branches/1.1 
http://restlet.tigris.org/svn/restlet
   git svn fetch

This takes a while (I've had to interrupt this) and this creates a 
number of branches such as:
   remotes/svn/tags/1.0b1
   remotes/svn/tags/1.0b2
   remotes/svn/tags/1.0b3
   remotes/svn/tags/1.0b3@1883
   remotes/svn/tags/1.0b3@323

What surprises me is that it looks like it's looping over and over, since sometimes it starts back from SVN revision 1 when it's trying to import a new tag.

Tt starts like this:

Show 11 quoted lines

> 
> Checked through r101
> Checked through r201
> Checked through r301
>       A       www/index.html
> r1 = 2ec77afc2e491e2b7c825cb685101e3bcbe7a8f7 (refs/remotes/svn/tags/1.0b1@312)
>         A       source/impl/License.txt
>         A       source/impl/Copyright.txt

>         A       source/impl/org/restlet/RestletException.java
> ...

Then, when it reaches r312, it starts again at r1:

Show 14 quoted lines

> r312 = 5b40558b5bb2b4b04f9520f89b699ff6b0f50cdb (refs/remotes/svn/tags/1.0b1@312)

>         A       source/impl/org/restlet/connector/Resolver.java

(And so on for each tag).

This seems particularly inefficient and unfriendly for the resource provider (I stopped as soon as I noticed). Is there a better way to do this?

Best wishes,

Bruno.
