This is just an observation; I've not investigated it at all. It appears that the ruby bindings tests are currently hanging on one of the buildslaves: http://ci.apache.org/builders/svn-x64-ubuntu-gcc/builds/3636/steps/Test%20bindings/logs/stdio
After an hour, the buildslave senses that nothing has happened, so it kills the test and moves on to other things. Since the bindings themselves haven't changed, and the symptoms look like a deadlock of some sort, I can only conclude that some kind of interference with the new svn_mutex infrastructure is causing problems. -Hyrum -- uberSVN: Apache Subversion Made Easy http://www.uberSVN.com/
