Actually in this particular case, for the synthetic linux target, we do
return to a prompt when a test program finishes, but only in the anonymous
CVS sources: http://sources.redhat.com/ecos/anoncvs.html

This won't happen by default for Hello World (the standard eCos rules
apply). You could do this instead by calling the function 

extern void cyg_test_exit(void);
