You could make a structure on the heap to track which threads you kill
yourself and which you think is alive - i imagine.
Each thread should then update said structure when done (in a
threadsafe way needless to say).
If a thread then is gone and your tracker thinks its alive you can
conclude something else killed it -almost in a portable way i guess.
