_ >   2331 2331 - updated documentation
  2332 2332 - reanimated NSF_PROFILE (when activated, needs more stack and slows execution slightly down)
  2333 2333
< >     2334 - fixed a problem with object-level alias
    2335 - nsf.c: provide low-level commands for managing profile data
    2336 - nsfStack.c: provide hook to obtain callers information in profiling code
    2337
    2338 - nx.tcl: provide caching for computed values of object slots to make
    2339   method objectparameter nearly twice as fast; direct changes on slots
    2340   require a reconfigure call.
    2341 - nsf.c: removed SUBST from shadow commands (does not appear to be
    2342   necessary any more)
    2343 - nsf.c: fixing a memory leak (some substituted values were not freed correctly)
    2344 - nsf.c: fix potential crash for epoched cmds
    2345 - some minor updates for profiling support

2334 2347 TODO:
  2335 2348
< >     2349 - serializer: check, why catch is needed for object-level alias
    2350   (search for ns_cache_flush)

< _   2336 2352 - NSF_PROFILE
  2337 2353   * provide an interface to clear and to output PROFILE data.
  2338 2354   * output should provide a cutoff value.
