Hmph.  Is "atomic push" so special that it deserves a separate
parameter?  When we come up with yet another mode of failure, would
we add another parameter to the callers to this function?

All other error message that come from the codepaths around here
seem to avoid uppercase.  Also maybe you want to use error() here?

This check logically belongs to the previous step, no?

The same comment as the other fprintf() applies here.

Why dashed-words-here?
