-----------------------------------------------------------------
File deletion is usually quite reliable on Windows as long as you don't have
aggressive virus scanners etc. running in the background.
For example, our filesystem tests create, write and delete files and we don't
seem to get spurious deletion errors on them.

> On Windows this fails:
> {code:R}
> library(arrow)
> write_dataset(iris, "test_dataset")
> # Original example was with DuckDB, but that's not necessarily the issue
> # con <- open_dataset("test_dataset") |> to_duckdb()
> con <- open_dataset("test_dataset")$NewScan()$Finish()$ToRecordBatchReader()
> file.remove("test_dataset/part-0.parquet")
> #> Warning in file.remove("test_dataset/part-0.parquet"): cannot remove file
> #> 'test_dataset/part-0.parquet', reason 'Permission denied'
> #> [1] FALSE
> {code}
> But on MacOS it does not:
> {code:r}
> library(arrow)
> write_dataset(iris, "test_dataset")
> # Original example was with DuckDB, but that's not necessarily the issue
> # con <- open_dataset("test_dataset") |> to_duckdb()
> con <- open_dataset("test_dataset")$NewScan()$Finish()$ToRecordBatchReader()
> file.remove("test_dataset/part-0.parquet")
> #> [1] TRUE
> {code}
