Precise confirmation would be nice -- a test perhaps -- would be nice. Felix, do you feel like writing a test that checks whether GC can happen while a foreign function call is ongoing? If we can confirm that ACL is the outlier, then (a) I'm all for changing cffi-allegro's implementation to match the semantics of the other Lisps and (b) documenting these semantics in the manual.
