Subject: Threads After Fork

Am I understanding this example right:

#!/usr/bin/env ruby -wKU

printer = Thread.new do
   10.times do
     sleep 1
     puts "Thread running in #{Process.pid}..."
   end
end

fork do
   p [Process.pid, printer.status]
   printer.join
end

p [Process.pid, printer.status]
printer.join
# >> [457, "sleep"]
# >> [458, false]
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...
# >> Thread running in 457...

__END__

Are all other threads stopped as part of a process fork?
