Not to me. I would expect catching StandardError (implicitly or 
explicitly) would catch everything I have a reasonable chance of 
recovering from, including timeouts. This is my standard strategy when I 
am not entirely sure what exceptions may be thrown by third-party code. 
There is code in the standard library that throws TimeoutErrors that 
need to be caught explicitly:

   require 'open-uri'
   begin
     my_file = open("http://www.example.com/file")
   rescue
     puts "Sorry, I couldn't open the URL."
   end

In this case, everything /except/ a timeout will be caught. This is 
inconsistent and confusing behaviour to me, especially as it is not 
properly documented anywhere that I have seen.
