6be94f2be stopped subtracting a negative intensity's Poisson term from the
background variance, but only in the host Combine(). The CUDA combine is the
path that actually runs: Run() selects it whenever a device is present and no
observation dump was asked for, so the correction never took effect on a normal
run, and a --dump-observations run merged differently from a normal one - the
two are meant to be identical.
