The attached script hangs on Ubuntu + Python 2.5.2.
When make the limit smaller (like 10) or not redirecting stdout, it works.

Running the svn command from shell took about 4sec, I gave up on the
script after a minute.

I tried it both with svn 1.4.6 and 1.5.1 - no change.

This is not a subprocess bug.  the os's pipe buffer filled up so the
process never terminated to be noticed by wait.  see:

use communicate() instead of wait().
