> Considering that the method _getTable(String)_ in
> _org.apache.hadoop.hbase.client.HTablePool_ is invoked by multiple threads,
> it may happen that while _'queue == null'_ is true, it is possible to have a
> queue mapped to that name into the tables map when _'tables.put(tableName,
> queue)'_ is executed.
> However, I don't think it will cause any harm because the overwritten queue
> will eventually be garbage-collected. :-)
