I updated the JIRA too, but the problem here is I think that the MacOS
runners have 1 CPU. I can reproduce on Linux and Mac by doing
`set_cpu_count(1)`:
```r
library(arrow, warn.conflicts = FALSE)
dataset_dir <- tempfile()
write_dataset(mtcars, dataset_dir, )
# change to set_cpu_count(1) to reproduce the deadlock
set_cpu_count(2)
open_dataset(dataset_dir) |>
dplyr::filter(mpg > 30) |>
head() |>
dplyr::collect()
```
