A couple of screen shots of how things look so far
both are of syscall observers, one added to firefox-bin,
and the other to a bunch of funit-child processes.

This model is timeless. One way time support could be added
is by adding an event loop 'tick' event to EventManager.

Events have an index, and as you can tell the events for a proc
is just the compilation of events of its threads.

Scrolling support is disabled as that is going to be part of the
histogram.

More to come:
- button for observers.
- button for blockers.
- maybe icon for status.
- Histogram of events.

Any thoughts/suggestions ?
