Not true - if you handle the SIGINT, there's no reason why you
shouldn't get a character in the input stream. Here's an irb session
on Windows:

>> trap(:INT) {}
=> #<Proc:0x02855d78@C:/Documents and Settings/dburt/Program Files/ruby/lib/ruby
/1.8/irb.rb:65>
>> require "Win32API"
=> true

=> 1
>> read_char  # and press Ctrl+C
=> 3
