Multiple X servers

A single JX application can connect to an unlimited number of X servers. The screen shot shows the JXDisplayMenu when an application is connected to three different X displays.

Unfortunately, this is only a quick-and-dirty solution because Xlib simply dies if any of the X servers crashes. The safe networking solution is to use JCore's networking support to implement a client-server pair, where the server is independent of X.

JX does provide protection against X server crashes, however, via JXFileDocument::SafetySave().
