Interrupting a thread

Sometimes, we need to kill a thread that has eaten too many resources or that is just executing for too long. For example, some parser works in a thread (and actively uses Boost.Thread), but we have already got the required amount of data from it, so parsing can be stopped. Here's the stub:

int main() {
    boost::thread parser_thread(&do_parse);

    // ...

    if (stop_parsing) {
        // No more parsing required.
        // TODO: Stop the parser!
    }

    // ...

    parser_thread.join();
}

How can we do it?

Getting ready

Almost nothing is required for this recipe. You only need to have at least a basic knowledge of threads.
