[D-runtime] A mechanism to kill threads

[Alex Rønne Petersen]

Of course it's unsafe, but no less than arbitrarily suspending a
thread. Once you've suspended a thread, you may as well kill it.
You've effectively halted it anyway. We have lots of unsafe primitives
in core.thread already (and my critical regions and cooperative
suspension patches add even more!).

Is there anything speaking against adding this to core.thread with a
big fat "THIS IS UNSAFE" warning?

Regards,
Alex
