svn log hang

Hi,

I recently upgraded my Subversion client from version 1.7.5 to 1.8.3 and
from that time on I experience hangs when executing multiple 'svn log'
commands in a short amount of time. The "hanging" svn process consumes
all CPU cycles it gets but never finishes.

I can reproduce the problem using the following shell script (on Windows
using Cygwin):

#!/bin/bash
ROOT="http://example.com/svn/trunk"
for DIR in $(svn ls "${ROOT}" | head -n 4); do
  svn log -v -l 5 "${ROOT}/${DIR}" 2>&1 | head -n 100 > /dev/null
done

In my environment I need at least 4 svn processes to achieve the faulty
behavior. The hang only occurs if the output is truncated using the head
command (but it can be redirected to a normal file instead of /dev/null
which then contains the expected log messages).

Regards, Stefan

P.S.: Could you please keep me CC as I'm not subscribed to the list. Thanks.
