Nil exitstatus

Hi,

With the following code (1.9.3-p125) I very occasionally find that @exitCode is nil...

    Open3.popen3(@environment, @command, options) do |stdin, stdout, stderr, wait_thr|
      ...
      @exitCode = wait_thr.value.exitstatus
    End

Does anyone know how I should interpret this? Dare I interpret it as success (ie equivalent to 0)? Or is it most probably just a bug?

Cheers,
James

% ruby -ropen3 -ve '
Open3.popen3("sleep 1") {|i, o, e, w|
  Process.kill :TERM, w.pid
  p w.value.exitstatus
  p w.value
}'
ruby 2.0.0dev (2012-03-16 trunk 35049) [x86_64-linux]
nil
#<Process::Status: pid 4079 SIGTERM (signal 15)>
