Subject: Re: long loops inside threads

Are you join'ing the thread? If not your main thread is likely to exit 
before the counting thread has.

 > cat /tmp/test.rb
require 'thread'

t = Thread.new {
   count=0
   while count < 10000 do
     puts "x"
     count +=1
   end
}
t.join


 > ruby /tmp/test.rb |wc -l
10000

 > ruby /tmp/test.rb |wc -l
10000

 > ruby /tmp/test.rb |wc -l
10000
