Subject: Possible ruby bug involving threads and IO

Hi,

I ran into a problem demonstrated by the following code :

#!/usr/bin/ruby 

require 'thread'

Thread::new {
  while true do
    puts "before read MOTD"
    str = IO.read("/etc/motd")
    puts "after read MOTD"

    puts "before read UPTIME"
    str = IO.read("/proc/uptime")
    puts "after read UPTIME"
  end
}

while true do
end

Ruby hangs on IO.read("/proc/uptime").

Note that it works with linux 2.4 (tested : 2.4.27) but not linux 2.6
(tested : 2.6.9)
It only fails with files on the proc filesystem.

Any ideas ?

Thanks,
