Richard, here is result (statistics was saved every 10 seconds):
live words - RSS:
186980 - 12380KB <-- after first 10 seconds of work
154156 - 18232KB
153923 - 19648KB
...
after 10 minutes of work:
203842 - 33436KB
170559 - 33528KB
187018 - 33664KB
71626 - 33592KB
Sometimes live words drops down to 40.000. But RSS always stay near
30-50MB.
