   I agree with @yandrey321 that there needs to be some tests here. The Seek 
logic has various boundary cases, eg:
   
   * seek to a position behind the current buffer 
   * seek within the current buffer
   * seek within the pre-read chunks
   * seek past all the pre-read chunks
   * seek to the start
   * seek out of range
   
   The tests should validate data read correctness, and that unnecessary reads 
are not issued to the server when relevant.
   
   To commit this code without tests is not going to help the next person that 
comes along, and this code is complex enough that its difficult (at least for 
me) to follow or review the correctness of.
