It is at least a good feature to fail when another instance of XWin.exe 
is operating on the same display number.  Your fix still allows running 
multiple instances like the following, right?

XWin :0 -query foo_host
XWin :1 -multiwindow
XWin :2 -fullscreen
...

As long as it allows the above and only fails if someone tries to do the 
following, then it will be fine:

XWin :0 ...
XWin :0 ... [should fail]
XWin :0 ... [should fail]
