Debugging this some more, it looks like the freeze appears at the very
end of the attach function, when it calls length(names(value)) on the
newly created object-tables environment. At this stage, calling
ls(value) gives the expected output, but calling names(value) or
length(value) triggers the freeze.

The NEWS file does mention that R 3.2.0 introduces some changes to
names(env) internals. Could it be that this somehow conflicts with the
object tables hooks?
