If the node should be reloaded, rather than giving it an entry in

last_reservation, and letting the reload daemon pick it up from there,
we schedule a reload and stick it directly into the reloadpending
experiment. The effect of this is that the node never ends up in
the free pool before getting reloaded.

(Note: We _don't_ do this if the node is being freed from the reloading
or reloadpeding experiment)

This change may not be permanent.
