sh function on windows hangs.
      The simple workflow script is

      node( windows-x64 ) {
      sh 'uname -a'
      }

      on the windows node cygwin is installed and on path for the node user.
      When run this hangs with the console output showing,

      [Workflow] Allocate node : Start
      Running on scaab053 (Windows 2012 R2) in c:\jenkins\workspace\Workflow_HelloWorld
      [Workflow] node {
      [Workflow] sh
      [c:\jenkins\workspace\Workflow_HelloWorld] Running shell script
      ...little spinning icon here....

      Having to use 'bat' instead of 'sh' would block the project as numerous global functions and DSL's use this.
