Hi,

I just updated to version 2.0. The chunk_size parameter of the read_delim_chunked function does not seem to work. Regardless of the argument that I pass, the chunk size remains fixed at 10000.

Thanks.

EDIT: Here is a reproducible example. Chunk size argument does not work when reading mtcars.csv:

library(readr)
f <- function(x, pos) print(nrow(x))
read_delim_chunked(file = readr_example("mtcars.csv"),
                   delim = ",",
                   callback = SideEffectChunkCallback$new(f),
                   chunk_size = 5)

The output is "32," indicating that all 32 rows were read at once.
