Found some time on the plane ride home to give this a shot. The attached
applies on top of the perf/core branch in:

    git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git

You can specify multiple threads or multiple processing using a
comma-separated list. e.g., -t tid1,tid2,... or -p pid1,pid2,... (not both).

It still needs more testing, but let me know how it works for what you need.

Arnaldo: would you mind scanning this and see if there are any major
problems/objections with the approach?
