begin  
Timeout::timeout(OverallTimeout) do |tl|  
# Until I find out what this is, Forget it…  
# No doc on tl anymore!  
#puts “tl: #{tl}”  
probe\_threads.each { |t| t.join }  
puts “done”  
end  
rescue Timeout::Error =\> eo  
puts “#{eo.message}, exiting before joining all probe threads.”  
end

Can anyone help? Is it deprecated perhaps?

According to the document[1], tl is same to OverallTimeout.

BTW, I noticed the 1.8.6 document[2] is wrong in block parameter.  
timeout(sec, exception=Error) {|if sec == nil or sec.zero?| …}

I guess it is related to the bug in the source code of 1.8.6 and 1.8.7  
The first line of method timeout  
return yield if sec == nil or sec.zero?  
should be  
return yield(sec) if sec == nil or sec.zero?
