URL: https://github.com/apache/arrow-rs/issues/614#issuecomment-886250668
🤔 though I tried to get a clean MIRI run against the parquet2 crate
```shell
(arrow_dev) alamb@MacBook-Pro:~/Software/parquet2$
MIRIFLAGS="-Zmiri-disable-isolation" cargo +nightly miri test -- --skip io
```
And I got some errors; I am probably running it incorrectly 😢
```
test read::levels::tests::test_get_bit_width ... ok
test read::metadata::tests::test_basics ... error: unsupported operation:
can't call foreign function: strerror_r

= help: this is likely not a bug in the program; it indicates that the
program performed an operation that the interpreter does not support
