Just saw this - catching Throwable is problematic : it could be any system
related Error's too : which might leave the VM in inconsistent state if not
properly handled.
Like an OOM or a link error. Are we sure ignoring Throwable is the right
approach here ? It is not just the current thread which might be at risk ? If
there is a more specific subset which is relevant, it would be more appropriate
to catch those.
