The main reason I was thinking for using MappedByteBuffer is that if 
you're accessing a large amount of sequence it won't necessarily all 
get loaded into memory at once.  This could, for example, make random 
access to a multi-gigabase sequence database bearable on a basic 
desktop computer.  Just a thought, not sure how much demand there is 
for this.
