I'd fetch it all at once into a single byte array and try Arrays.equals()
GetLong has to get it a byte at a time still to support endianess.
Id have to think about it, but what you really want is to get it all
into a byte array and then process it in 64bits. AIR there are some
new array recasting things in Java 5+. Ill need to go look at them

It's always darkest just before you are eaten by a grue.
