Hi,

As far as I can remember, no version of git svn has ever relied on
orphanable objects.

Of course there are unavoidable race conditions that happen while git
svn is running.  It is never safe to run repack concurrently while git
svn is running (I wouldn't repack/gc simultaneously with _any_ write
activity on the repo).   git svn itself can/will run "git gc" in-between
revisions if needed.  You can safely repack manually whenever git svn is
not running.
