In general, I agree, but I have my own hunch which is that if writing is
fast they'll be much more written to than if it's slow ;-) So basically,
I don't want to have to assume that writing is slow if it can be avoided.
BTW, thanks for all the pointers, ideas, and other comments. I really
appreciate the discussion and I am still in the midst of thinking about
a good implementation. I'll share my thoughts later.
