Yes, that's my take on it too. I think something useful could be added
to, say VxWorks (taskHookLib) by a user implementation. But to
acheive really good accuracy, I suspect will take the compiler vendor
and OS provider to provide.

For Win32, access the Task Manager Performance could be a useful
implementation and again, for real accuracy, I suspect it's  up to the
compiler vendor and OS provider...
