* lisp/org-clock.el (org-x11idle-exists-p): Only shell out when running on X.
The definition of this variable currently executes "command" via the shell during evaluation, irrespective of the platform on which Org-mode is running. Unfortunately, on Windows, this matches the "command.com" NT Virtual DOS Machine executable and so this gets launched, but this is a shell and therefore sits there waiting for user input and never returns. The net result is that Emacs will hang on Windows when evaluating org-clock.el with the ntdvm.exe process spinning at 100%. The simple fix is to check that the platform is X before trying to deal with the "x11idle" external process.
