Thanks, this is exactly what I'm looking for. In 2.6.32 (Ubuntu 10.04)
it works, although if I use --pid rather than the -- <command> variant
the first thread seams to be missing. In 2.6.38 (Ubuntu 11.04) the
first thread is missing in both use cases, and I get one column per
processor (which in itself is fine).

Regards,
Wim
