[RndTbl] Neat tool - lsofgraph

[Adam Thompson]

I'm laughing because I've written the same tool for RPM, DEB, OpenBSD ports, Solaris pkg and HP-UX.
And at least the first 3 of them now have a built-in (or at least in the repo) tool for doing it.  You'd think it was a common task for sysadmins or something :-)
