Sorry, I wasn't clear. I'm not disagreeing with you, just suggesting 
that timeouts could be sensitive to location on the stack. Poorly said, 
but this is what it comes down to in code (not sure if this would break 
anything in stdlib though):


require 'timeout'

class StandardTimeoutError < StandardError; end

module Timeout
   def self.standard_timeout(*args)
     timeout(*args) {yield}
   rescue TimeoutError
     raise StandardTimeoutError # maybe muck with the backtrace first
   end
end

begin
   Timeout.standard_timeout 1.0 do
     begin
       sleep
     rescue # inner
       puts "this should not happen"
     end
   end
rescue => ex # outer
   p ex
end
