The main problem is that pure Scheme implementation double memory usage (half of memory reserved for coping GC), a full search index tree contains about 2M nodes (approx 40*2MB).

This should be easy to workaround using the mmap interface in the posix egg.

Not sure i get it, you propose to put Сhicken heap into memory mapped file?

Ah, no, I meant store just the index in mmapped memory so it doesn't take up heap space.

This does mean it gets treated as just a blob of data, and you need to write your own routines to access it.

Some gc's allow moving objects out of the heap or otherwise marking them non-movable, we could consider such an extension for Chicken.

I think this is not so easy as it sound, at least for me :]

This is what the wish list is for :)

Anyway, just some minor comments, not trying to argue for or against Chicken in your next project.

Reports of issues from real-world applications are rare and invaluable to us, thanks!
