Another day, another release!  The previous GeeXLab  0.27.1.0 has been badly compiled. So many demos didn't work with this version.   

GeeXLab 0.27.2.0 adds one important thing to Python: the support of the GIL (Global Interpreter Lock). So Python scripts launched in a separate system thread work correctly.
