as I understand the threshold is reached when gc starts freeing the same 
amount of memory as it allocates? and because of it consumption 
stabilizes? So adjusting or restriction of this threshold in more 
complex applications is something very hard. And it's possible that if 
application suddenly gets data more than before application may crashes 
because this threshold oversize than available memory?
