You could do that with OSProcess. Presumably you could make this an
administrative function in a Seaside application if you wanted to
occasionally reopen the display on an X server (enter password, specify
X display, click OK).
"Connect the Squeak display to a different X window display"
OSProcess thisOSProcess displayOnXServer: 'willy.nilly.org:0'
"Connect to the local X display"
OSProcess thisOSProcess displayOnXServer: 'unix:0'
"Make Squeak go headless for five seconds, then reappear"
OSProcess thisOSProcess decapitate.
(Delay forSeconds: 5) wait.
OSProcess thisOSProcess recapitate.
