I think we'll need to use
reference counting, or simply not pool the byte[]s after
flushing, in order to avoid overwriting of arrays.

Can we just have IW allocate a new byte[][] after flush? So then any open
readers can keep using the one they have?

> The current *BlockPool implementations aren't quite concurrent.
> We really need something that has a locking flush method, where
> flush is called at the end of adding a document. Once flushed,
> the newly written data would be available to all other reading
> threads (ie, postings etc). I'm not sure I understand the slices
> concept, it seems like it'd be easier to implement a seekable
> random access file like API. One'd seek to a given position,
> then read or write from there. The underlying management of byte
> arrays could then be hidden?
