Actually, Daemon or not, any Threads run during the start lifecycle 
should be brought down during shutdown.  With very few exceptions, the 
state of the VM should be the same before the server has started and 
after it's stopped.  For instance, what happens when we do a restart and 
you've still got Threads hanging around?

Every subproject should take a look at the Thread dump attached to 
JBAS-6919 and bring down any jobs you've still got running.

An example of clean shutdown is Scott's work in JBAS-6929.  DML also 
tells me that anything using the jboss-threads project binds the Thread 
lifecycle to MC, which would cover these cases.
