The big question is: Do we want this added to an 0.8.3-rc4 ?

[fjy]

@drcrallen I think it is fine for this to wait.

[xvrl]

@fjy in that case we should mark roaring as unsafe to use in 0.8.x?

[gianm]

I think 0.8.3-rc4 is appropriate, as roaring is not an experimental feature so bug fixes are important.

[gianm]

0.8.4 would be cool too.
