Using standard Ada, you can measure "wall clock time" for each task,
with Ada.Calendar. In each task, store the start and end time, by
calling Ada.Calendar.Clock.

But if the tasks interrupt each other, this is _not_ the per-task CPU
usage.

There is probably a Win32 API for this. Go to
http://msdn.microsoft.com/library, and search around. When you find
it, see if it is already imported in the GNAT Win32 bindings. Then see
if you can make it work :).
