This is actually a serious question to the Java cogniscenti: how to
generally interrupt a running thread without its cooperation. Java 1.2
has made some improvements in this regard, and your milage may vary,
but you may find that Thread.interrupt() will do what you
need. interrupt() is now SUPPOSED to immediately terminate blocking
reads, wait() calls, etc., via an InterruptedException. You can
combine interrupt() calls with polls to interrupted() in your
Thread.run() method. Whether this works or not depends at this point
on the quality of the VM implementation in use. Note that there isn't
much that Jess can do to help matters.
