updates 2001.05.13

Folks, as ever, a few things checked in; the highlight
follows...  (If you want to know *exactly* what's flying
past, I suggest you subscribe to the ark-commits list.)

Two little scripts in sidai/gen-utils, cpustat and diskstat;
these are "site-at-a-time" versions of 'top' and 'df'
(essentially).  I like 'em; you don't have to :-)  Would be
nice to complete the set w/ a front-end to 'ntop' (network
top) [if it weren't a security-bug farm].

--help output first (below), then sample runs.

% PYTHONPATH=$ark/ARK/arkbase ./cpustat --help
cpustat [options] <host1> [<host2...>]

--interval=n    Refresh every n seconds; default 60
--count=n       Run n times; default -1, meaning continuously
--per-host=n  	Show n top processes per host; default 5
              	--per-host=0 means 'all'.
--all         	Synonym for --per-host=0
--threshold=n   Show processes with CPU usage above n%; default 30%

% PYTHONPATH=$ark/ARK/arkbase ./diskstat --help
diskstat [options] <host1> [<host2...>]

--interval=n    Refresh every n seconds; default 60
--count=n       Run n times; default -1, meaning continuously
--threshold=n   Only show partitions above n% full; default 80%
--all         	Synonym for --threshold=0
