Python 3.10: wait_for() got an unexpected keyword argument 'loop'

[drzraf]

On Python 3.10

NB: I add to switch to latest 'cffi==1.15.1' to complete the pip installation with 3.10
NB: INSTALL file mentions a Python<3.8 restriction due to #2769 which was actually assumed solved (as the latest comments indicate).
