I believe the idea behind the current code is that reset() gets called 
to make a writable message readable. Whether this is required or not I 
can't say for sure, but as pointed out at the start of this thread it 
should allow users to invoke it multiple times once the message is 
readable though.

I think we still want to check whether the message is writable, and if 
it is call _data.flip(), if it isn't call _data.rewind(). i.e. along the 
lines of:

     _readable = true;
