You could use the filesize and loop through all the full blocks and use a
seperate read for the last possibly incomplete block of data.
Even better you could use the seek function to determine how much was
read. A seek() should not add any overhead and would also handle the event
that the filehandler reads random amounts of data, though unlikely except
in case of EOF.
