We don't use `jinja2` at all, so either this is some kind of weird effect on garbage collection (a timing issue?), or `dask` is doing something differently as soon as `jinja2` is available.

Edit: most likely this is a timing issue... the offending line tries to make use of the internal `acquire` function, which I think at that point has already been destroyed. To fix that, I think we need to somehow store a reference on the file manager?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1695028906

- download and unpack the files from https://github.com/pydata/xarray/issues/7814#issuecomment-1535168128
- use `mamba create -n test python=3.11 xarray netcdf4` to create the environment (note: no `dask`)
- use `pip install ""dask[array]""` to install `dask` (does not pull `distributed` like the package from `conda-forge`)
- put the code into a script and execute it

For reference, the full traceback is:
```pytb
Exception ignored in: <function CachingFileManager.__del__ at 0x7fbdb237b430>
Traceback (most recent call last):
  File ""/home/jmagin/.local/opt/mambaforge/envs/test/lib/python3.9/site-packages/xarray/backends/file_manager.py"", line 246, in __del__
TypeError: 'NoneType' object is not callable
```

As far as I can tell, this means we're using something from `distributed` with a broken fallback, since the error goes away as soon as I *install* `distributed`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,1695028906
