Bug#1064326: python-xarray: intermittent hang in test_roundtrip_coordinates

[Rebecca N. Palmer]

Package: python3-xarray
Version: 2023.12.0-3

The xarray autopkgtest sometimes (~10% of the time) hangs in 
test_roundtrip_coordinates, and hence fails with a timeout.

Example failure log (but this is _not_ specific to pandas 2.x):
