Anyone here that can help suggest what specific info is relevant to grab
(and maybe even have a script to do it).
Personally I use lessdisks, where this info is also easily grabbed.
Such a process-usage-dump script would probably be useful also to
investigate servers: Ask the local admin to do a dump while serving lots
of clients (or while they experience that slowdown on the thin clients
that they were puzzled about) and us developers can investigate it
without needing access to the specific Skolelinux network.

...which is the reason for LTSP 3 not being part of Debian!
