These tests don't do multiprocessing, but do test the ability to capture output indeed. Is there a way with alisp.exe to redirect dribble output to the stdout console?
No, but I have never personally seen a situation I couldn't work around this issue. (alisp is a Windows program and they can't have bindings to stdout/stderr/stdin.) alisp.exe using dribble => temp file => use temp file in chain of pipes => remove temp file.
In this case, we're specifically relying on the console interface to run tests against various implementations and report results on the console. Certainly, we could provide a wrapper for Allegro only, but that would be a stretch. So far as I can tell, Allegro is the only implementation solving this issue that way in Windows.
