I ported Qi II to ABCL some time ago (a year?). IIRC it needed some
tweaking related to its (mis)use of the reader. I submitted the patch
to the Qi mailing list, but I don't know if it ever got applied, or if
it diverged since - I'm not a Qi user, I ported it just to get ABCL a
little publicity ;)
0.24 doesn't have the "large file" problem anymore, and anyway "large"
meant many more than 85 functions.
I'm not aware of any problem causing infinite loops when loading compiled files.
