  SVN rev 202992 on 2010-01-25 23:37:49Z by gabor
  
  Cache failing and opened catalogs in catopen() and related functions.
  Continuous catopen() calls cause 4 failig stat(2) each, which means a lot
  of overhead.  It is also a good idea to keep the opened catalogs in the memory
  to speed up further catopen() calls to the same catalog since these catalogs
  are not big at all.  In this case, we count references and only free() the
  allocated space when the reference count reaches 0.  The reads and writes to
  the cache are syncronized with an rwlock when these functions are called from
  a threaded program.
