it is a nice tool for me when i am useing it on windows 2008 64bit 。because low memory and cpu taken

my question is that when triflejs.exe --render=myurl opened more than 2 process in the same time, for example 5.(all 5 can be seen in taskmanager) the result will be only 1 or 2 page really visited（by web log） most work process lost!
can this be solved？
