With terminating, fork, exec and clone observers on nautilus, and then making
it fork, it prints into the background:
Call stack is broken - couldn't unwind!
ptrace: No such process

Which is likely caused by either the process not being blocked properly, or
some other inconsistency with the Task being unwound.
