Did you see this in svn_fs.h?

  * Only one thread may operate on any given filesystem object at once.
  * Two threads may access the same filesystem simultaneously only if
  * they open separate filesystem objects.
  * @note You probably don't want to use this directly. Take a look at
  * svn_repos_open() instead.
  * @since New in 1.1.
svn_error_t *svn_fs_open(svn_fs_t **fs_p, const char *path,
                          apr_hash_t *fs_config, apr_pool_t *pool);

In my multithreaded Python Ice Subversion server, I have a pool of
svn_fs_t's that are checked out and checked back in per RPC request. If
the pool is empty, I just create a new svn_fs_t.
