I wonder what happens if one has a kretprobe on an cunning function
(sys_delete_module), which indirectly may end up trying to remove the
probe (unregister_kretprobe) during its execution (systemtap probe
cleanup).  In other words, how does the kretprobe logic handle the
removal function, when the entry half of a return probe has been hit,
and the return part is pending?
