Garbage collecting CAFs

[John Meacham]

I have seen numerous references to CAFs not used to being garbage
collected in ghc leading to various contortions of the optimizer to keep
from generating them and possible space leaks... then "something" was
done and they are now collected.. I am curious what paper (or list
message?) describes what that "something" is and what it entails in
terms of tradeoffs. thanks.
