Johannes did not like a config option so I proposed it here as a
constant (like SWAP_CLUSTER_MAX and others we have). This is a value
that we have been using in our data centers for almost a decade, so it
has seen a ton of testing. I was hoping Johannes would get time to
take a look, or Nhat would get time to test it out, but neither of
these things happen.

I obviously want it to be merged, but hopefully someone will chime in here :)
