Thanks for the excellent explanation. Increasing the buffer size does work.
A dumb mistake is also obvious in retrospect. I had written a
fold-right (recursive) function, and even when the incoming "kons"
converts NSStrings to scheme strings, a full chain of recursive calls
(and objc:instances) will be built before any konsing occurs at all.
Since I was just using the fold function in ns:array->list and
ns:dictionary->alist, I changed it to a fold-left (iterative) and
tacked a reverse onto the ns:array->list. Et voila, a large array of
NSStrings converts immediately. You do still have to watch out for
unconvertable objects, for example an ns:array containing 5607
ns:dictionaries requires that much finalizer space as a list. (That
example is plucked straight from my iTunes Music Library.xml file; I
found this problem while writing some plist code.)
