I don't understand. Do you mean josef wants someone to fix
multithreading or do you mean he is doing that as part of
an allocator fix he is working on, or did you mean that
his work is an exception and you really were not looking at
doing any allocator changes?

I see this in your 0.16 list:

> Better in-memory free space indexing (Josef)

but did not tie it to the allocator. Is that it?

and I'll add an area I missed before in the Development_timeline:
- Fallocate support (at least disk format level)
as part of the allocator bundle-of-too-much-work :)
