Also, in case it's not obvious, when you see something like
%% ps | grep rio
rob 13 0:04 0:46 1280K Rendez rio
rob 133 0:00 0:00 1280K Pread rio
rob 134 0:00 0:00 1280K Pread rio
rob 135 0:00 0:00 1280K Rendez rio
rob 136 0:00 0:00 1280K Pread rio
rob 137 0:01 0:01 1280K Pread rio
rob 138 0:00 0:00 1280K Await rio
rob 153 0:00 0:00 1280K Await rio
rob 193 0:00 0:00 1280K Await rio
rob 863 0:00 0:00 1280K Await rio
rob 1721 0:00 0:00 1280K Await rio
rob 1828 0:00 0:00 1280K Await rio
rob 2191 0:00 0:00 1280K Await rio
%%
that 1280K is almost entirely a shared single copy of
the memory. The only part not in common is a single
page (most likely) of per-process stack.
In other words, don't add up the memory column of
ps to decide how much memory is in use.
