not sure if balance_pool can cause that.

Probably.  Ultimately, I think the problem is shards.  We've made some
recent changes that might make this happen less...

On the topic of the numbers there's this:
$ atest host list -b os:cros | grep -v pool: | grep board: | count_labels -b | sort -n | tail -10
      5 lulu
      6 veyron_jerry
      7 kevin
      7 stout
      7 sumo
      7 terra
      8 sand
      9 parrot
     10 heli
     10 rikku

How do we plan to handle these DUTs?

We'll re-add them to pool:suites, once I've done some sanity checks.

OK.  All the DUTs that seemed safe to have pool:suites got it.

There's a handful of DUTs that for various reasons couldn't be
added:

... and, once again, pool: label assignments seem to get
lost or mislaid.  We're back to some DUTs that ought to have
labels not having them:

    $ atest host list -b os:cros | grep '^chromeos[246]-' | grep -v pool: | grep board: | grep -v chameleon | wc -l
    18

At the time of c#5, the count was 0; a week later, 18 DUTs have lost
a pool: label.

For the moment, we can pump out the leaky boat _again_:

$ atest label add -m $M pool:suites
Added to label 'pool:suites' hosts: 
	chromeos2-row3-rack4-host5, chromeos2-row3-rack5-host5,
	chromeos2-row4-rack9-host10, chromeos2-row4-rack9-host11,
	chromeos2-row8-rack1-host3, chromeos2-row8-rack1-host5,

	chromeos4-row8-rack6-host7, chromeos6-row1-rack15-host11,
	chromeos6-row1-rack16-host15, chromeos6-row1-rack23-host15

$ atest host list -b os:cros | grep '^chromeos[246]-' | grep -v pool: | grep board: | grep -v chameleon | wc -l
0

... So, I'm declaring victory.
