When an x2go session is suspended, any running GUI-based application
will stall as soon as it tries to update graphical information in the
GUI.  This was not the case with the old freenx server, and it is a
problem for large jobs that take a long time to run.  Not sure if this
is just a configuration/install problem.
What does NOT stall:
 - Text-based output from command line-based shell scripts.
 - GUI-based applications running in suspended x2go sessions as
Published Applications.
What DOES Stall:
 - GUI-based applications running in suspended x2go sessions (accessed
by X2GoClient) on a Linux Desktop (i,.e. MATE, XFCE)
 - GUI-based applications running in suspended NX sessions (accessed
by an NX3 client) on a Linux Desktop (i,.e. MATE, XFCE)

The steps taken to produce the bug:
 - Start a GUI-based Application (for testing, use the Linux System
Monitor, open the "Resources" tab)
 - Suspend the x2go session.
 - Some time later, resume the session.  The GUI now continues
running, but it had stalled while the session was suspended.
