Subject: Re: memory leak

Well, seems I found solution...
I tried to make some test on python as well. Simple script, previously 
posted, eat memory on python too... and the only way I had it to use 
forks. I checked out forkoff, but produce some strange bugs. This is the 
working code:

threads = (1..THREADS).map do
   Thread.new q do |qq|
     until qq.equal?(myLink = qq.deq)
       mutex.synchronize do
         puts ($n +=1).to_s # + " : " + print_class_counts.to_s
       end
       fork   # <----- You need to fork it, after exit fork will release 
memory
         begin
           agent = WWW::Mechanize.new{ |agent|
           agent.history.max_size=1
           agent.open_timeout = 20
           agent.read_timeout = 40
           agent.user_agent_alias = 'Windows IE 7'
           agent.keep_alive = false
           }
           page = agent.get(myLink)
           puts myLink
           puts page.forms.length

           page.forms.each do |form|
           end
         rescue
         end
       end
     end
   end
end
