Python test_async_io fails on GDS-enabled system

[kingcrimsontianyu]

# <my_gds_supported_path> below represents a GDS supported file system.
# Note that in the dev container, the temp directory must not be the default /tmp.
# The default /tmp is an OverlayFS, which would cause cuFile I/O to have "internal errors" at runtime
export TMPDIR=<my_gds_supported_path>
pytest ~/kvikio/python/kvikio/tests/test_async_io.py -x

On a GDS-enabled system, the above test yields the following error:

python/kvikio/tests/test_async_io.py:36:
