Answer: 
In the "Debug" perspective, there is a "Debug" view which shows the threads of the application being debugged:

There's a little menu in the top right corner, with an option "Show Debug Toolbar". Select that, et voilá:

If any of the watch expressions takes too long to evaluate, those mentioned buttons will appear to be grayed out during the evaluation. In such case removing all watch expressions will help.
