IO-wait time now counts as idle time, which is a more

accurate description. It is still available in
split time, now called detailed CPU time.

* CPU affinity configuration ('a' key)
* Improve display of tree view, properly nesting
threads of the same app based on TGID.
* IO-wait time now counts as idle time, which is a more
accurate description. It is still available in
split time, now called detailed CPU time.
(thanks to Samuel Thibault for the report)
* BUGFIX: Correct display of TPGID field
* Add TGID field
* BUGFIX: Don't crash with invalid command-line flags
