What's the conclusion of your discussion? It seems you want some
statistic before deciding whether to  ripping the bitmap from the ABI,
am I right?

I think Andrea and David feel pretty strongly that we should remove the
bitmap, unless we have some data to support keeping it.  I don't feel as
strongly about it, but I think their critique of it is pretty valid.  I think the
consensus is that the bitmap needs to go.

Thanks for you clarification.

The only real question IMNHO is whether we should do a power-of-2 or a
length.  But, if we have 12 bits, then the argument for doing length is pretty
strong.  We don't need anywhere near 12 bits if doing power-of-2.

So each item can max represent 16MB Bytes, seems not big enough,
but enough for most case.
Things became much more simple without the bitmap, and I like simple solution too. :)

I will prepare the v6 and remove all the bitmap related stuffs. Thank you all!
