We use Spawner instead of java.lang.Runtime because :
- old java VM on windows used to spawn a dos window for each Runtime.exec();
- for gdb to interrupt the debugging process you need to drop a signal, SIGINT.
- Signals are not available in Java.
- and more recently it allows us to provide terminal emulation (not on all platforms).
