ah, very sorry to have reported a duplicate, reportbug didnt propose me 
this bug when reporting, i had looked previously on 
https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=python-eventlet and 
didnt find an already reported issue.

Well i've installed python3-eventlet 0.26.1-7+deb11u1 from that url on a 
testing environment, commented my /etc/hosts workaround, restarted the 
mapproxy gunicorn pool, and can confirm that it also fixes the mapproxy 
'Lookup timed out' issue (which makes sense, since greendns.py has the 
content from 0.32.0 so it's equivalent to my previous patch)

Many thanks for your work on tracking this !
