Hm.

--8<---------------cut here---------------start------------->8---
    token = CNFSMakeToken(cycbuff->name, offset, cycbuff->blksz,
                          (offset > cycbuff->free) ? cycbuff->cyclenum - 1
                                                   : cycbuff->cyclenum,
                          cah.class);
--8<---------------cut here---------------end--------------->8---

I think this might be interesting part, especially "offset >
cycbuff->free" condition, (maybe "=>" inequality?), but this is probably
far shot.
