Well, you can capture the signal, but the problem is not the signal itself but what caused the problem. The most common case of segfaut is memory corruption (and thus a program that tries to wrongly interpret wrong addresses). If you already corrupted the memory doing something wrong, how can you "fix it"?

I think important case here is creating wrappers for new C libraries. Common mistake is passing wrong structures to foreign function. Then image crashes and you need restart it and recover code - big waste of time and losing smalltalk liveness.
