tcl/tk is cross-platform; there's no reason that a tcl-coded
performance monitor client couldn't run on Windows or Mac.

The real problem with the ps-based implementation that Bruce is
proposing is that it cannot work remotely at all, because there's
no way to get the ps data from another machine (unless you're
oldfashioned/foolish enough to be running a finger server that
allows remote ps).  This I think is the key reason why we'll
ultimately want to forget about ps and go to a shared-memory-based
arrangement for performance info.  That could support a client/server
architecture where the server is a backend process (or perhaps a
not-quite-backend process, but anyway attached to shared memory)
and the client is communicating with it over TCP.
