Description

Currently we can't enable SO_REUSEADDR in the IPC Server. In some circumstances, this would be desirable, see explanation here:

Rarely it also causes problems in a test case TestMiniMRClientCluster.testRestart:

At least for testing, having this socket option enabled is benefical. We could enable this with a new property like ipc.server.reuseaddr.
