BUG: Fixing case in which the pointer the data buffers doesn't 

get positioned at the beginning of the buffer after a new
     buffer load. This case only happens when the pointer happens
     to be at the end of the buffer when the request for the new
     block arrives.  Fix contributed by Bill Hoffman.
