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
