> The junit test failed when iterates a number of times with larger chunk size on Linux.
Once a while, the visible number of bytes seen by a reader is slightly less than what was
supposed to be. 
> When run with the following parameter, it failed more often on Linux ( as reported by
John George) than my Mac:
>   private static final int WR_NTIMES = 300;
>   private static final int WR_CHUNK_SIZE = 10000;
> Adding more debugging output to the source, this is a sample of the output:
> Caused by: java.io.IOException: readData mismatch in byte read: expected=2770000 ; got
2765312
>         at org.apache.hadoop.hdfs.TestWriteRead.readData(TestWriteRead.java:141)
