Not that I'm discussing against the import -J switch, but the compiler 
is also running inside a sandbox. At least it looks like:

(my interpretation: compiler crashes inside the sandbox)

Conclusion: the compiler doesn't need to be safe. Actually, using a 
sandbox approach is probably more secure than trying to fix all compiler 
security issues.
