It should be possible to have other threads interacting with the GUI as
long as they do that by sending messages to the thread responsible to
for GUI. Here's an example of an SWT snippet that does GUI manipulation
from a different thread:
http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet130.java
On line 42 a new thread is created. On line 48 the GUI is changed, by
adding a string to some text widget. But this happens using the
"display.syncExec" method. This force the code to be executed on the GUI
thread instead of the current thread.
