Both ast.parse() and ast.literal_eval() can trigger a segfault with the appropriate string input due to the recursion depth limit of the AST compiler.

Got approval for the wording from @serhiy-storchaka in the issue itself, but he also pointed out that there are implicit uses of the troublesome functions in various other places, so the comment needs to spread out a bit more before this PR can get merged.
