This is a problem that we'll be solving in upcoming releases. The idea
is that you should be able to break out of a blocking call by interrupting
a thread using Thread.interrupt(). The blocking call will be terminated
with an InterruptedException and a flag in the thread and Thread.interrupted()
will be true. The thread should then be given a change to cooperatively
terminate. If that fails you can try Thread.stop() which will throw
a ThreadDeath exception.
We unfortunately didn't have time to finish this before the release went
out.
Have fun,
Arthur van Hoff
