I made a few changes to allow only one sysinfo process display on
the software label lines on your currently active window. The only
drawback to this is that the software labels of the User Agent, or
another process that displays labels, will be over written by the
sysinfo information.
There might be a delay between the window manager's window activation
and the new display of the information. This depends on how fast the
window manager creates the new window (system load). The SIGWIND
signal is caught, and a new CURRENT window is gotten, but if the system
is slow it will still be the old window. In that case the information
won't be displayed until the sleep(SLEEP) is done.
Apply the following patch with "patch" :-)
