I'm thinking to just call display-warning then (removing the element
looks like too much work to be worthwhile, having to modify the list
while iterating over it is kind of annoying).

I noticed that display_malloc_warning passes intern ("emergency") as
the LEVEL, but it should be intern (":emergency") (with a colon),
right?
