I tracked this down to a low ulimit setting on the particular jenkins
host where this was failing (max processes).
Specifically the following test was failing on trunk, but not on
branch 3_3, which concerns me
./src/java/test/org/apache/zookeeper/test/QuorumZxidSyncTest.java
there haven't been any real changes to this test between versions, any
insight into why the server is using more threads in trunk vs
branch33?
