  On most systems, it will be swapped away in that case. (Whereas
if the logic is in the kernel, that memory cannot be swapped.)

  If your system doesn't have swap, then it's probably some embedded
box and you likely won't hotplug many things, so you can use
Natanael's approach: use an event listening daemon for the coldplug,
then kill it and register a /proc/sys/kernel/hotplug helper for the
rest of the system's lifetime.
