One thing.
If thread to be aborted is currently asleep or is waiting, then it's not possible
to interrupt it this way - it will continue to wait after SetThreadContext/ResumeThread.
One possible solution is to use alertable APIs, such as SleepEx to implement Thread::Sleep().
Then use asynchronous notifications to ensure interruption.

Like this:
    SetThreadContext(hThread, &new_ctx);
    QueueUserAPC(empty_function, hThread, NULL);
    ResumeThread(hThread);
