Comment(by augustss):
If this problem can't be fixed in a generic way, I'd like to request two
things:
* Mark garbage collected CAFs so that if they are ever used again the RTS
can give a good error message. I'd like to spare other people tracking
down this bug again. It was tedious.
* Add a function setKeepCAFs() that can be called outside the RTS. It's
much more reliable to have a function to link against in the RTS than just
a symbol to set (I failed in several ways to set keepCAFs from outside the
RTS.)
