Some of you where probably wondering what I found weird: I'm not
surprised that 1.2.2 doesn't handle asynchronous stops.  I am
surprised that synchronously delivered stop exceptions don't carry any
stack trace.  I'm also completely at a loss to explain when stop works
in 1.1.7.

Does anyone think that Thread.waitOn should emulate jdk behavior and
clear out the stack trace from a Thread.stop() exception before
throwing it?

wait 1 second before calling Thread.stop()

wait 0.1 seconds, but 0.8 works too.
