  * Writes HFiles. Passed KeyValues must arrive in order.
- * Currently, can only write files to a single column family at a
- * time.  Multiple column families requires coordinating keys cross family.
  * Writes current time as the sequence id for the file. Sets the major compacted
  * attribute on created hfiles. Calling write(null,null) will forceably roll
  * all HFiles being written.
