[Pharo-dev] catching FFI errors

[Ben Coman]

I had a brief moment wondering about the general problem we have when 
calling out through FFI that we expose ourselves to bugs in the external 
library that crash the Image.  I wonder...

1. Debuggers like gdb can run a program that crashes, without themselves 
itself crashing.  Could our FFI calls be wrapped in similar mechanism?

2. Languages have exception handling, so that errors like divide by zero 
can be caught.  Could our FFI calls be wrapped in similar mechanism?
