delayed expunge and subfolders

[Leena Heino]

In the cyrus.cache file there are always 10 cache fields per message. But 
what could cause this code in mailbox.c to fail in the middle of skipping 
over those fields:
  /* Compute size of this record */
  cacheitembegin = cacheitem = mailbox->cache_base + cache_offset;
  for (cache_ent = 0; cache_ent < NUM_CACHE_FIELDS; cache_ent++) {
      cacheitem = CACHE_ITEM_NEXT(cacheitem);
  }

I see this failure when I try to use cyr_expire with -X 1 or with any 
number greater than zero.
