Bug#1001424: python-nest-asyncio: (autopkgtest) needs update for python3.10: TypeError: gather() got an unexpected keyword argument 'loop'

Dear maintainer(s),

We are in the transition of adding python3.10 to the supported Python 
versions [0]. With a recent upload of python3-defaults the autopkgtest 
of python-nest-asyncio fails in testing when that autopkgtest is run 
with the binary packages of python3-defaults from unstable. It passes 
when run with only packages from testing. In tabular form:

                       pass            fail
python3-defaults       from testing    3.9.8-1
python-nest-asyncio    from testing    1.5.1-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of python3-defaults 
to testing [1]. https://docs.python.org/3/whatsnew/3.10.html lists 
what's new in Python3.10, it may help to identify what needs to be updated.
