 Replying to [comment:29 rhaas]:
 > Question for Ian: did you not also experience some issues with svn and
 very parallel checkouts where you tried to checkout each folder in a
 repository individually? Ie. IOUtil/src IOUtil/doc ... ? Speaking of
 fixes, I don't think that the priority option that Frank suggested is a
 good solution. While it may work and is simple to implement would seem
 quite hard to set up and requires a lot of user intervention (as in us
 having to come up with correct priorities). Instead GetComponents should
 be able to deduce priorities itself if at all possible.

 SVN changed it's on-disk representation of working copies (see, e.g.
 http://stackoverflow.com/questions/1364618/how-do-i-determine-svn-working-
 copy-layout-version) several times.  In one of these changes, they
 switched from having a .svn directory in each subdirectory to having one
 at the top level (like git).  As far as I know, with this change, you can
 no longer update subdirectories of an SVN repository in parallel (also
 like git, unfortunately).  Additionally, since each checkout creates a new
 http(s) connection, you might run into the web server's configured limit
 if you attempt very parallel checkouts.
