Doesn't happen over here as the attached script shows:

$ ./exec-nowait.gbs3
0.00100183486938

The Print line is executed obviously without waiting for the command to
complete. Does it work the same on your system? If not, there is a bug in
your copy of Gambas. If yes, it must be something deeper in your code.
