That race condition is already present with the leader election in the
Reaper itself as it could lose leadership after scheduling a check for some
time in the future, so this is at least no worse than the current state of
things. And the race condition doesn't matter too much anyway as the reapers
don't use leader election for correctness, but rather because otherwise you get
a bunch of logspam about trying to delete already deleted nodes.
