Description

in FollowerHandler if sendPackets gets an ioexception on writeRecord the send thread will exit, however the
socket isn't necessarily closed.

2009-08-19 15:28:46,869 - WARN [Sender-/127.0.0.1:58179:FollowerHandler@131] - Unexpected exception
at org.apache.zookeeper.server.quorum.FollowerHandler.sendPackets(FollowerHandler.java:128)
at org.apache.zookeeper.server.quorum.FollowerHandler.access$0(FollowerHandler.java:107)
at org.apache.zookeeper.server.quorum.FollowerHandler$1.run(FollowerHandler.java:325)

This results in the follower taking a very long time to recover and rejoin the quorum.
