The issue is that if you append to such an array and it adds more pages
in
place, the block length location will move. Since each thread caches
its
own copy of the block info, one will be wrong and look at array data
thinking it's a length field.
Even if you surround the appends with a lock, it will still cause
problems
because of the cache. I'm not sure there's any way to reliably append
to
such data from multiple threads.

Would assumeSafeAppend() do the trick?
No, that does not affect your cache. I probably should add a function to
append without using the cache.
