Whatever the cold load draws from the default random source is frozen
into the band it produces --- comparator.scm's hash salts, for instance ---
so entropy there makes every band, and everything later compiled from it,
differ between builds.
Seed it deterministically. Restoring a band has never reseeded, so a
given band has always handed every process that runs it the same
sequence; this only changes which one. (That it does so at all is a
separate bug: (random n) returns the same value on every machine running
a given band.)
