 St^Ack: Sorry I was away. It is just spinning
 shrijeet: I had wr itten a nice sequence of events , but then pastie.org decided to go down
 shrijeet: anyways, here is the sequence 1) Launch a scanner which is slow, example scan hits once in billion 2) see entry in rs active calls list of type 'next'
 shrijeet: 3) as soon that next call hits 60 second mark one more entry in rpc call list appears, this new rpc call is 'close'
 shrijeet: 4) client does not see the exception untill close hits 60 second mark
 shrijeet: 5) client dies once it sees exception (after 2 minutes) but next and close continue remotely
 shrijeet: 6) they hang out in active call list of >30 minutes then they go away, region server spits our some warning in between
 shrijeet: The warnings being org.apache.hadoop.hbase.UnknownScannerException, org.apache.hadoop.ipc.HBaseServer (output error) etc.
 shrijeet: Here is a JSON snapshot of the state I described in (6) http://pastie.org/3842252
