I understand the problem, but on my Windows box your change has three problems: 1. svn export uses 100% CPU, because serf call throttled_handle_xml_parser all the time. Because APR_POLLIN is still enabled in pollset. 2. Memory usage didn't change on my tests, svn export of svn-trunk still uses 50MB of memory 3. Time of svn export increased from 50s to 120s. -- Ivan Zhakov
