Here's a possible approach:
Instead of launching another CCL Image in the event of an error, make
the IDE a separate application from the start. It would include
Hemlock, the Backtrace dialog, the Inspector and various other tools.
The IDE would never run code itself. It would communicate with a
separate Lisp process using something like the Slime/Swank protocol.
It the event of an error the Lisp doing the work could sit happily in
its break loop, while the IDE managed events and displayed the
And there is no reason for the IDE to be strictly CCL. It could, in
fact, be a Cocoa based Slime, supporting various Lisps and even Schemes.
