I have a project that is quite large. I'm not sure if it's coincidental or not, but since upgrading to 1.428, I've been getting a number of intermittent build failures, that actually fail in the cleanup stage deleting files from the previous build. My svn settings are set to 'clean checkout' although I also get this problem if I select 'revert and update'. Is it possible to make this stage more tolerant of locked files (perhaps by increasing the number of retries?)
