Class Thread
Creates a handle to a new thread. The handle can be used to kill the thread or be ignored. The function provided is executed after an initial timeout. Note that although this looks similar to the setTimeout in web-browsers, after started, the thread will not run until completion but run in parallel to the executed script.
To stop the script from within a thread, use exit(). To stop only
execution of the thread (silently) throw a null exception
("throw null;"). To terminate the script with an exception
throw a normal exception ("throw new Error("my error");").
Note that a running thread might consume all CPU. Although it is
a seperated thread, JavaScript allows only one thread to run at
a time (thus it can make programming simpler, but is not really
consuming more CPU). In certain circumstances, it might be necessary
to give CPU time with v8.sleep(...) back to allow other threads to run.
