The only downside listed is "Users will no longer be able to use LD_PRELOAD
to override a symbol from libpython".

Does anyone know if that is an issue for gentoo?

The big problem with this proposal is:

- How To Test

-- Test that everything Python related in Fedora works as usual. 

I don't even know how to find "everything Python related" on Gentoo.
And then, for each package that may be related, it would be necessary to
test all its features.

Maybe a better way would be to grep the gentoo repository for
"LD_PRELOAD", but I don't think I have the capacity for that.  Anyone?
