Subject: timeout and gets on windows, or user error?

I'm sure this is my misunderstanding, and/or possibly a known thing,
but when I put a 'gets' inside a timeout block, it blocks forever.

Is this a known windows issue?  (XP, if that matters)

Here's test code that does what I expect:

===============
require 'timeout.rb'

$stdout.sync = true

begin
  timeout(5) {
    1.upto(10) { |x|
      puts x
      sleep 1
    }
  }

rescue TimeoutError
  puts "too much time taken"
  exit 1
end

==================================

It spits out 1 to 5, then the too much time taken.  Fine.

When I use THIS however...

====================================
require 'timeout.rb'

ans = ""
$stdout.sync = true

begin
  timeout(5) {
    print "enter name:" 
    ans = gets.chomp
  }

rescue TimeoutError
  puts "too much time taken"
  exit 1
end

puts "name is #{ans}"

==================================


it sits at the prompt forever.  (Interestingly, if i enter a name and
wait past the timeout period, I DO get the error printed, but I'm
forced to actually enter something.  Even MORE interestingly, if I
enter NOTHING and wait, but just hit return (after the timeout), I
get no error.)

Pointers?


Thanks,



Mike
