CI: Azure timeout debug
Parallel troubleshooting with https://github.com/pandas-dev/pandas/pull/45507#issuecomment-1018536106

Possibly a candidate for the hanging behavior: https://github.com/pandas-dev/pandas/pull/45389

Maybe the `os.unlink(fname)` call? Yeah from the logs maybe the teardown step is hanging?

yah in the other PR i short-circuited the pyarrow case and it got past this OK, but now looks like its hanging on a totally unrelated offsets test. @mroeschke still needed?
