Parallel SVN update process

I need to execute several SVN update processes in background under same folder structure as I have many subfolders and want to speed up whole thing.

I have folder structure like this:

/folder/subfolder1/
/folder/subfolder2/
/folder/subfolder3/
...
/folder/subfolder1000/

I'm trying to do something like this in bash script:

svn up /folder/subfolder1 &
svn up /folder/subfolder2 &
svn up /folder/subfolder3 &

Problem is in that SVN complains that '/folder' is locked and only first task finish correct, other two don't and got error message like this:

svn: Working copy '/folder' locked
svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)

Is there a way to accomplish task on this way with several parallel SVN process because doing one by one folder (selected by some other process) takes a lot time to finish?

P.S: I'm doing all this in higher programing language (PHP-CLI) but for simplicity of question I write it as bash script (got same problem).

In older versions of Subversion every subdirectory had its own .svn file. If your svn is old enough, and you run the commands in the subdirectories, then I think that won't lock the parent directory and the commands can succeed in parallel. Like this:

(cd /folder/subfolder1; svn up)&
(cd /folder/subfolder2; svn up)&
(cd /folder/subfolder3; svn up)&

Although, to be honest, I thought your original command should work too, I don't see why the parent directory gets locked.
