### Describe the bug, including details regarding any error messages,
version, and platform.
I've encountered a situation where calling .to_table() on a
pyarrow.dataset.Scanner causes the process to hang indefinitely.
```
import pyarrow as pa
import pyarrow.dataset as pd
import pyarrow.parquet as pq
t = pa.table({"col": 'pyarrow'})
pq.write_table(t, 'table.parquet')
pd.dataset('table.parquet').scanner(fragment_readahead=0).to_table()
# never returns
```
Note, that the data to read is minimal and the following works:
```
import pyarrow as pa
import pyarrow.dataset as pd
import pyarrow.parquet as pq
t = pa.table({"col": 'pyarrow'})
pq.write_table(t, 'table.parquet')
pd.dataset('table.parquet').scanner(fragment_readahead=0).head(100)
pyarrow.Table
col: string
----
col: [["p","y","a","r","r","o","w"]]
```
