The policy has always been to know what you're doing in gc
handlers. Not use shared resources in particular. Not yield. Not
try to grab new resources. This is why, specifically, on_shutdown
triggers weren't implemented - it's impossible to make them both
generic and safe.
While this series perhaps won't harm, I doubt they will help much
if the user is a rookie.
