Hello,

I think 
	vastart += 2*1024*1024; 
is weird.
if we look /proc/$ip/segment in share(), we will have better solution.
but I am not convinced we should apply the solution.
because we seldom needs shared segment.

I haven’t had any trouble with telnetd.
I needed shared segment for special purpose in my program (Pegasus).

thanks
