    Description

      Mina server gets into a bad state where it constantly prints :
      WARN org.apache.mina.core.service.IoProcessor - Create a new selector. Selected is 0, delta = 0

      when this happens, server throughput drops significantly.

      to reproduce run the attached server and client for a short while (30 seconds on my box).
