Add PSS from /proc/PID/smaps, better <0 differences, Minor fix
Add proportional set size (PSS) reporting from Linux /proc/PID/smaps file.
Better bug fix for differential reports with differences < 0 (as happens a lot with PSS, actually, due to sharing dynamics). procs d -d1
really does seem nicer than top
to me..It's certainly more general.
Correct the nowNs
field width.
