It's possible to do that in C++. If you are happy with the results you get
from 'C' (no resource cleanup, etc.), you could simply kill the thread
unceremoniously using the same facilities that 'C' programs do. There's
nothing about C++ which makes this infeasible. It's not that "we can't do
that", it's that we want to do better. Remember, 'C' programs /also/ have
resources allocated which they plan to deallocate upon returning from
functions.

How would you like the compiler to account for it?
