IIRC, Dyalog uses something like quad-EMX for extended error messages.
(I used their Linux product; I have no idea what they do on the PC.)

That said, I'll throw in my opinion regarding Emacs: It seems most
appropriate to use the message area even for multi-line messages. (The
message area automatically expands as needed.) If you need to recall the
message later, just visit the *Messages* buffer.

Personally, I'm not fond of popping up a new buffer. That's really what
the message area is for...
