Conflict With md5 names for output files

Hi guys. I found another race condition for scripts that have the same output. May be this problem is resolved in new version ?

My script:

require 'winrm'
require 'winrm-elevated'

code = "Get-Host"

endpoint = 'https://winrm.example.com:5986/wsman'
winrm = WinRM::WinRMWebService.new(endpoint, :ssl, :user => 'VP_DNS_Account', :pass => 'password', :no_ssl_peer_verification => true)

winrm.create_executor do |executor|
  elevated_runner = WinRM::Elevated::Runner.new(executor)
  result = elevated_runner.powershell_elevated(code, 'VP_DNS_Account', 'password')
  puts "Std out: #{result.output}"
end

My ERROR:
